spark plugs
plug wires
fuel filter
air filter
I've been running Valvoline Synthetic with Fram high mileage oil filters. Recently I started researching oil filters and just realized how bad some of the FRAM filters can be.
I am pretty happy with valvoline but somewhere I read Pennzoil synthetic is actually better? I don't want to spend the money for Amsoil but what do you guys recommend for synthetic oil? Or should I just stay with Valvoline?
What oil filter should I use for my next oil change? I want a high quality oil filter, I only change my oil very 6,000 - 7,500 miles.
What other maintenance things should I do on the engine? I have done the 3M complete fuel system cleaner once ( Amazon.com: 3M 08963 Fuel System Tune-Up Kit: Automotive) and then since then I've been running chevron fuel cleaner at every oil change.
I also am thinking I need to do a complete coolant flush (I didn't flush the entire system when I changed the water pump)
and I'm thinking about a new filter and tranny fluid for the tranny.
What else should I do? at a 180,000 miles this tahoe still runs great and I am hoping to get another 60 - 80k on it.. |
Oil filter.....Mobil 1, K&N, AC-Delco....Stay away from Delco filters with the number ending in "E", Example, Get a PF46 NOT a PF46E.
Im guessing "E" stands for economy...Very poor construction.
Im a Oil is Oil guy. If Valvoline is working for you stick with it. I run Mobil 1, But I couldnt show any proof its better than any other leading synthetic. Neither can anyone else. Dont believe marketing hype.
I have different veiws on ATF.....
Stay away from Dexron VI ATF, It has caused seal damage in some transmissions that were made before 2006, GM says its backward compatible, But they will not fix any seal damage after warranty
RUN Dexron III. The ONLY Dexron III fluids to have a OEM licence are TES 295Fluids approved by Allison. GM DOES NOT licence Dexron III ATF at all.
TES 295 Approved Automatic Transmission Fluids.
Castrol/Allison........................TranSynd
BP Lubricants.........................Autran Syn 295
Cognis Corporation..................Emgard 2805
International..........................Fleetrite Synthetic ATF
ExxonMobil.............................Mobil Delvac Synthetic ATF
John Deere & Company.............HD SynTran
Volvo Trucks North America.......Bulldog Synthetic ATF
Cheap Aftermarket Dexron III fluids are labeled DEX/MERC, And are NOT approved by any OEM.
Change the fluid in the rear diff, Any good Synthetic 75W-90 will work.
Other than that follow the maintenance schedule in the owners manual.
