Which oil filter do you use?

[Z Factor]

There are many to choose from, so which one do you use and why?

As always, if yours is not listed post it and I will amend the poll to include it.

I use the Bosch 3401 based on an article by Marc H. in the current newsletter.

[jonszr1]

I tried the bosch had more chain rattleand oil pressure was alot less when warm. I had the same prob. with the mobil one. don't know why? but I put on a napa gold and no chain rattle and the oil pressure to 3/4 instead of 1/2. would love to find out why.

Jon that is intresting I use a Mobil1 and my Pressure is around 3/4 and I was thinking it might be a little high (but I guess not) and I don't think I have any chain rattle. I am thinking about going with a Bosch though next time I change the oil. anyone esle have an opinion on this?

[91King]

I have been using Mobil 1 filters for over three years with no chain rattle. In view of Marc's article I may try the Bosch the next time I change oil.

[Jason 91]

I too use the Bosch based on the article by Marc H. on his web site.

[BBBAD94ZR1]

Was using Mobile, actually purchased a case of them If anyone wants to buy them I'll sell them cheap. Pm me. The reason for the change is poor performance:thumbsdo: . I did a test took of the filter let it sit over night all the oil drained out. To confirm this I cut open the and all the was gone[-X .
I had some cam chain rattle that I never had before.:icon_scra New batch of filters? I put on the Bosch filter changed the oil. No rattle, higher oil pressure;) . I took off the filter did the same test oil remained in the filter as it was suppose to:thumbsup: . Did some further reasearch I found the mobile1 filter is actually made by Champion. That explains that....
Use what you will as this is only my opinion and observations I made.

Ray, which M1's? The old grey ones or the new black ones?

[Z Factor]

I do not want to influence the poll but I must ask this question. For those of you using the Mobil 1 filter that are not having any chain rattle, why would you want to switch to Bosch?
Granted I also read the article by Marc, and while I respect his knowledge and advice, I have used a Mobil 1 without any problems. As I recall it was rated as one of the best for filtration with it's synthetic media.

Ray, just an FYI. Bosch is also made by Champion Labs.

[BBBAD94ZR1]

Jeff,
It was the new black ones, I purchased them around 2 months ago.
Ray

[BBBAD94ZR1]

As Bosch being made by Champion I was unaware. I found a case of old filters from 4 years ago. My uncle owns a shop and had them in a warehouse. All I kwow is what I seen. When I had the filters that came with the car when I purchased it where old mobile ones painted black. The new ones seemed to be the issue.
Thanks for reading.

I switched to the Bosch after I started having trouble with the new black M1 filters. I had been using the old grey ones & I had good readings on the gauge and very slight chain rattle upon cold start up. On warm or hot restarts there was almost no chain rattle.

My first oil change for the start of the summer the A/Z by me had the new black M1's so that's what I bought. Major chain rattle on cold start up, minor rattle on warm/hot restarts and an alarmingly long time to have O/Pres show up on the gauge. I was very concerned that my O/Pump was quitting on me. I bought another black M1 & tried it and had the same results....now I was scared!

Came home(here to our home) and looked around & read the newsletter at the netreg site and decided that I was having some bad luck with the new black M1's. I was going to order another O/P sending unit but buying a Bosch O/F was quicker. All I can say is using the Bosch instead of the black M1 my "noises" at cold start & warm/hot restarts are back to what they used to be when I was using the grey M1's. Quick rise of O/P @ start up on the gauge and very little chain rattle @ cold start. My 90 always had about 3 seconds of chain rattle at cold start as I doubt the original owner ever complained enough while under warr for the dealer to replace the right side guide? Anyway, it always had about 3 seconds of rattle after sitting a week. Warm &/or hot restarts had practically no rattle and the O/P gauge always showed a quick (you almost didn't notice a wait for O/P) build to operating oil pressure.

I guess the A/Z where I buy M1's got a bad batch??? The grey ones worked fine, it's the black ones I had bad luck with so now it's Bosch for my Z! I know that this is unscientific but the nosies & time to build O/P were giving me nightmares!:mrgreen:

How much you want for the case of filters?

[bobbyhi]

I have been using the Bosch and no chain rattle....

Hib - good to hear from you on the forum. Wish you were here more. You have a lot to contribute.

[90ZR1]

wow... so many mobil 1's.... maybe ill try and switch, see if she feels better!

[Hib Halverson]

Hib - good to hear from you on the forum. Wish you were here more. You have a lot to contribute.

Thank you, Bob.
I wish I could get here more often, too. I'm going to try better on that in 07.

[DaveK]

Has anyone ever tried the re-usable ones like the Pure Power one?

http://www.gopurepower.com/site/products/default.asp#FILTERS

Just curious - they look like a good idea 'on paper' at least and got a pretty good write up in 'Vette' a few months back.

Dave

[4DSZR1]

I've been using the M1 and a couple months back I went with a Bosch. According to my highly claibrated ear, the Bosch may be a tiny bit better on cold startups after siting a week or so, some minumal rattle. Startups after just a few days are noticably better with no rattle at all.

[A26B]

M1 cuz I like 'em.

[Jagdpanzer]

Bosch - great performing filter, besides having that cool all black "Johnny Cash" look after removing the label.

[janozr1]

K&N , because it is white with nice sticker on :p

[HIZNHRZ]

At this point, I'm using whatever I can find.

[karterdon]

I noticed that no one is using the Delco filter ?? I use it on mine and havevery little if any chain rattle, even affter the car sits for several weeks and no rattle when warm.. Good Oil pressure. Any reason why you are not useing the OEM??:confused: :confused: :confused:

Blackstone labs says my oil is clean so skicking with bosch.

Did notice from cutting them open they have changed thier design within the last year or two and they look better now, totally different check valve design.

Don, speaking for me...I can get the Bosch easier than I can get the A/C Delco stuff. The autozone is near the costco so it's a bunt, one round trip = oil & filter!:mrgreen:

Better filtration with the Mobil 1, even though the OEM is good.

PurePower reusable, no rattle that I can detect.

[kirkstingray]

Bosch all the way I trust Marc H he knows. AC is all I used in the past, some will work ok some did not.

[ZRXMAX]

On a related subject.... I see Mobil 1 is $21 a jug at Wallmart... not bad for 5 quarts.

YA BUT... You don't need a Mobil 1 filter... I use the Bosch... Autozone carries them.

BTW... Walmart is over $2 a quart cheaper for Mobil 1 oil than Autozone

[Chad N Swartz]

I read on Marc's site the Bosch drains thru the check valve after 24 hrs, so I'm gonna try the Wix from NAPA

[PhillipsLT5]

Thats new updated Marc info

[Dime]

The previous owner used Bosch and that's what I'm going to continue to use. No rattle from what I can tell, pressure comes up quickly, oil stays clean.

I've only owned the car for about two months so my opinion doesn't really matter.:p

[bobbyhi]

I will be switching from the Bosch to the WIX (NAPA) per Marc's new recommendation.....

[Gunny]

I've been using the Bosch for several years, but I've noticed more chain rattle with the last 2-3 ... Marc's new info just confirms this. Makes me wonder if Bosch has "changed" their filters. Shame, I liked the look of the Bosch with the label removed. I will be trying alternatives soon ... may even change to another filter in the next few days even tho I changed oil/filter a couple of weeks ago. This last Bosch filter has more chain rattle than any filter I've used.

Mine is not even shown. Valvoline oil filt.
But I also have some Frams.

[USAFPILOT]

I use Mobil 1 Extended performance and the Mobil 1 Filter that goes with it. No chain rattle or weird oil pressure readings on my 54000 mile LT5. I get it all at advance auto parts which normally does a deal on the mobil1 which gives you 5 quarts and a filter. I buy two kits each time and have some extra filters. Each time I also have an extra quart, so pretty soon I'll have enough quarts and filters to do it for nothing, sort of.

[LancePearson]

I just bought two of the Napa 1324 Wix filters yesterday for my future oil changes. They looked them up and their data said they have the check valve as reported and a 16 pound bypass pressure. Most of the things I've bought from Napa are reasonable performers for the l48 1976's engine and now this one. Followed Marc's rec.

[Schrade]

Isn't this mill (LT5) bulletproof?

Seems that if you do the oil & filter change every 3k, or 3 months, whichever comes FIRST , then even a budget filter will get the job done... (unless the hammer stays on the floor for track use).

I owned a fleet for courier & delivery that I ran, and did the O/C about every 10 days for all of them, for many years, which was roughly, 3k, and all the vehicles kept a good squeeze under the heads. The last one, an Express 1-ton 5.7 bought new '02 as my own personal, had ZERO squeeze loss @ 205k...

[LancePearson]

just out of curiosity when you reset the oil change on the dashboard, how many miles before it comes on saying to change? My 2008 TBSS calculates oil wear so it's not miles at all. How does this one work, straight miles or sensors inputs for varied use?

Manual did not say as far as I can tell.

I use the AC PF970 with oil change every 2000 miles.

[Paul Workman]

I use the AC PF970 with oil change every 2000 miles.

Every 2000 miles on an oil change? Is that something you do once in the spring/start of the new driving season as a matter of routine, or ??? Just curious why the cadence is so high. Even in the DINO OIL days, 3000 miles was the norm, and that was with a 5 quart oil pan; including the filter. With full synthetic it is much higher - e.g., 5k and then some, depending on application.

Paul,

The oil changes pretty much coincide w the driving season. I always change the oil for the winter. When I am getting ready for a long drive and/or racing situation as in going to BG, I change the oil prior to that event. The Castrol GTX I use is not SYNTH oil. I usually throw in 8-9 quarts/change w filter.

"We also found that the NAPA 1324 filter retains eight ounces of oil after the engine is off for 24 hours. The filter is white in color and is made by WIX."

The above is from the H site oil filter recommendations page - Color is off but this is the one I use. Good price as well.

I have been using the 1324 for a while now. Thing is sometimes we get a 1324 that doesn't hold oil in it overnight.

I have found Marc to be very knowledgeable when it comes to the ZR-1, he changed my injectors some time back and car has ran great. He recommends Bosch oil filter and have used them ever since with no problems.

[ZR2]

Just picked up a 94 and it has an STP filter on it now. I have 2 Bosch filters ready for when my wife finds out I bought the car.......she does not kniwcyet.......SO in my house. Once I break the news Mobil 1 synthetic oil and the Bosch filter.

[Great White]

I've cut open many different flavors of filters from my old RX-7 to see how they are constructed. (I know it's not a Z but the filters are cheaper and I don't mind using it as a guinnea pig) K&N is one of the best filters money can buy, hands down. But it's pricey. Wix is my filter of choice for every vehicle I own, because of the construction/build quality and the number of pleats inside (bang for the buck here.) I get mine from Amsoil when I buy a case of 10w40 for my Z.

[Mr.Yuck]

I agree oil Filtration is obviously a number one concern with any oil filter but the main reason for our talk about the oil filters on the LT5 is which one has the best anti-drain backvalve to help prevent timing chain rattle on some LT5's at startup because of the inverted oil filter design.... The older BOSH oil filters I experience Zero chain rattle but the newer Bosh filters still part number 3401 I get timing chain rattle. I still have a few of the old design with the Orange colored anti-drain backvalve and it works perfect. I have experimented with the new design were the anti-drain backvalve is black and It rattles ever start up. It's like flipping a light switch with the difference..17127
