Mobil 1 High Mileage - ZR-1 Net Registry Forums

Funracer · 03-02-2013

Decided to go with Mobil 1 High Mileage mostly due to easy availability.

Viscosity questions now.

My 91 came (I think) with 10w30. In 92 or so the factory
changed to Mobil 1 5w30. M Haibeck suggests Amsoil in 10w40.

Mobil 1 HM comes in all three of these (and other) viscosities.

I live in North Florida so not too cold normally.

Should I go with 5w30, 10w30 or 10w40?

Thanks

I don't take any recommendation from Marc Haibeck lightly. His recommendations are always backed up with considerable research and experience - with the ZR-1 and the LT5 in particular! Marc recommends AMO 10w-40 (with the levels of ZDDP present in the oils originally used in the LT5 at the time of its introduction, by the way).

Just sayin...

Newer engines are built with tighter tolerances (use lighter oil).
High Mileage engines loose tolerances (use heavier oil).
Hot climates (hotter engines) thin oil (use heavier oil).
Cold climates (colder engines) thicken oil (use lighter oil).

Often starting colder engines (lighter oil).
Running engines for long hauls once started (use heavier oils).

Newer synthetic oils do not loose viscosity with use (use lighter oils).

In Fl or CA coastal (use heavier oils).
In SD winter ....definitley (use thinner oils).
Frequent oil changes (use thinner oils).
Infrequent oil changes (use heavier oils).

i think my civic call for 5w20 or something like that. It's basically water

I agree with you Cliff about viscosity and climate; having said that like Kevin said, I had a Honda that was 5W-20 and my Mercedes was 0W-40 per manufacturer. I think there is nothing wrong with following what the manufacturer recommends when it comes to viscosity and a lot of times the owner's manual will tell you different viscosity to use based on the climate of where the car is.

I use mobil 1 synthetic extended performance 5w-30

He listed Mobil HM as acceptable and it is far easier to come by. My
local NAPA guy (he owns the store) is an Amsoil dealer. He could not find Amsoil AMO in his computer. I drove to Walmart and they had Mobil 1 HM in no less than 5 different viscosities.

I bought the 10w40 because Marc recommended that weight for the Amsoil. I just wondered if that or some other weight is best.

Thanks

The way I read all that for me the heavier oil is best then.

Thanks for your time

When SGC did my engine work Aaron recommended Mobil 1 15-50 because of the high ZDP content. Plus in NW Fl it doesn't get that cold and it is available at nearly all auto parts stores.
