I know this topic is always going on every forum but couldnt find one on here. So i know the 5.7L wants it meals served with 5W-20. So i went to my local walmart and was overwhelmed with oil. I have been putting in Mobile 1 full synthetic for years now and will only use that. But to my surprise Mobile 1 makes 3 types of 5W-20 now. There is just the normal silver one, a blue high mileage one, and a gold extended performance one. Im doing the oil next week and wondering if anyone knows the difference or used the other two? Also Fram has a Ultra synthetic oil filter. Any good?

I cant say say too much about the differences in the mobil 1s

For oil filter info take a peak at:

I use royal purple oil synthetic and a k&n oil filtre myself.

It may just be a marketing thing. I go straight Mobil 1 regardless of mileage and haven't had a problem since I started with in back in 1995.

I fed a GM LT1 Mobil 1 for over 140K miles and it still looked super clean and the mains were in excellent shape.

Thanks for that helpful link man. It is interesting. Makes me think a Fram decision is a horrible one, Ill probally just get a Mopar filter.

Pennzoil High-Mileage 5W-20 in mine. I never had a problem with Fram filters. I use the K&N filters.
