What weight/type oil do you run?

[ChrisAU]

Yeah seemed like the value of it was best, and I wanted something heavier than 10W-40 but wasn't quite ready to jump to 20W-50 haha. Plus for this oil change the fact that the Delo comes in a 4 quart bottle was great since my 5th quart will be MMO.

I know that you already made your choice but I thought I'd throw what I use out there as well.

I only run Castrol GTX 10-30. IIRC the previous (and original) owner told me that he ran Castrol 10-30 as well so I stayed with what he used. It seems to work great. I run it all year round. In the winter we occasionally see <0 F temps but normal winter temps are 10-30 Degrees F. In the summer we rarely see temps above 90.

No by all mean everyone keep posting, I went through all the pages and was surprised I didn't see a similar thread. This is a basic bit of information that we need to have available here!

You guys using the AC Delco filters should check out the oil filter study thread I bumped...

agreed, they changed who makes them a few years back and their quality is not there anymore.

I'm glad I found it, I was going to go from Purolator to AC Delco this time and felt good about using what I thought would be an upgrade...
