Re: What oil and filter to use
 

I've been using the NAPA filter and Mobil1 oil. At the next chage I'm going to try the Bosch filter and switch to AMSOil as recommended by Marc Haibeck.

Re: What oil and filter to use
 

went on different websites and Bousch seems to be the filter to get. I proably will order one tomorrow.

Re: What oil and filter to use
 

The bosch filter has the best check valve in it and keeps most all of the oil in it. This helps to protect the right side cam chain tensioner, because oil presure is there already. Other filters the check valve does not work very well and all your oil drains down. This may not seem like a big deal but over a thousand or so starts those seconds of dry parts start taking a toll.

I took the NAPA filter off. there was oil still trapped inside. I let it sit upside down and very little oil came out. So the check valve does work in that fliter. I put a NAPA filter back on.
