I have been using regular Mobil 1, a week or so ago I put Mobil 1 High Mileage in it since Walmart was out of regular Mobil 1 5w30. I would say now I'm closer to 8-9k a year, I've moved a lot and some years have drove 15k and others 5k. Is the only benefit to synthetic the longer OCI? I changed...

I'm looking for oil recommendations for a 99 Silverado 4.8 with 215,000 on it. The truck is old, and shows its age but so far has been 100% mechanically. I've had the truck for about 5 years and 50k now, and have been doing oil changes every 3k, plus previous owner had oil changes done every 3k...

It would run 200-230 with the 195 in it. When you're 10 miles of hard trails from the truck you don't wanna risk running hot. With the 130 it runs at 130 if I go easy. Hits a Max of 150 now. I have leeway for running even hotter should something go wrong. I know it controls the min temp not the...

I run nothing but pf52 on my Chevy 1500. I like if awful well. The pure one is what I run on the jeep, and it does very well also. I'd prefer the AC delco myself for a GM product.

I'm new so don't hurt me too bad but is there a way to see used oil analysis for different oils, maybe even by motor? I know the 350 Chevy tbi and the 4.0 both would be easy finds due to them being so common. After a little more reading I'm liking the 10w30 rotella t5 for the jeep. Still not...

Lol thanks, she's got a few miles but I bought it one owner from a man who has been around cars about twice as long as I've been alive. I believe my next change is going to be either the Pennzoil or rotella t5. Might look at mobil super or Valvoline next Gen for the truck.

Thanks guys. The reason behind the 130the degree stat was the overheating I'd get into with the factory cooling system and I just threw it in with the rest of the upgrades. Ill look into the Mr gasket ones for sure. I've got Mr gasket thinner head gaskets to bump up compression slightly and they...

First things first. I've been reading this for a while after trying to find what oil to run in my girlfriends 2013 cruze. I absolutely love how the site gets into the scientific side of stuff being a chemical engineering student. Anyway... I read the entire motor oil university and have some...
