It's the good stuff, thin when it's cold, thick when it's hot, shear stable and high additive. I have gone from driving 5,000 km a month to barely using a tank of gas a month in my personal car, so at 10,000 km OCI, this will probably last me a year.
Filter is Fleetguard StratoPore LF3554. Oversized filter for more capacity, although I overfilled the engine about 10 ounces to get all five litres in. The Fleetguard filter interested me because it seems quite similar to the media in Amsoil EaOs, so I bought it from Cummins. The thing is a beast, and it barely clears the back of my AC compressor.
What are you using and why?
Current Fill: Quaker State Horsepower 5W-30.
Why?: The dealership I have used for years shut down their Chevy shop. The Chevy dealership in the next town over I went to after that also shut down. That leaves the closest Chevy/GM dealer to me almost an hour away and they are 1st class JERKS who enjoy tormenting customers! The other 2 dealers had no issue with me running Royal Purple even though it is only API SL. I actually had already swapped the engine over to RP but swapped it out for the QS after the 2nd dealer shut down. Those 2 dealers realized it is excellent oil( ie; SL )and will not hurt the engine in anyway. Unfortunately, my manual calls for SM oil( API Starburst actually which means SM ). So, to avoid any hassle from the new dealership, with just 8K on a 2008 vehicle, I swapped over to QSHP which is both GM6094M approved and is SM. I always liked Quaker State oil so it was a good 2nd choice for me.
Filter: AC Delco
Why?: This engine seems to be very picky about filters or you get a lot of engine "clatter". Was running a Napa ProSelect and the engine sounded like it had no oil most of the time. Swapped back to the AC and noise went away immediately. I am going to try Bosch, Hastings, and STP filters to see what they do. May stay with the AC as they are cheap at WalmMart and AutoZone but I have never been a fan of them.
