I am new to owning a big block Chevy and just bought a 86 bounder with 65,000 miles on it and want to change from petro based oil to synyhetic. 1st question is what is best synthetic to use and what grade. 2nd question is the oil filter appears to be the canister type that is vertical to the back of the engine on the drivers side. does anyone know what make of filter is best and the part # for the filter? Thanks Chuck
I have searched & searched and cant find much discusion on the matter. Can anybody else respond? I would like as many pro's & con's as possible. Thanks
Thanks Mike I might try the 1 quart of syn and see how it does. The only reason I was going to change is I was told synthetic would give me more power and my engine would run a little cooler.
If it was my rig I would just stick with the petro oil,use a good name brand and change it often.You can get a larger filter from NAPA its about a quart larger.I tried synthetic oils a few times with engines that had a few miles on them.I got oil leaks and after fixing leaks went back to petro oil.Maybe ok on a new engine from the start.Maybe someone else here may have had good luck with but not me.I wave a mechanic friend that for years mixes in one quart of syn. with the petro every oil change works for him. I like NAPA gold filters a buck or so more but worked well for me on a 95 ford van with 287 k miles a few years ago,now over 300k i am sure. Good Luck Mike
I have used synthetic oil in 454 and had best results with lower mileage engines. On the higher mileage engines, I had better results with Slick 50. I am in the process of getting another motorhome with 454 and 23000 miles and I am going to change it to Royal Purple 10w30. I found that after using 15w40 in one that it was a mistake. The cam wears out tooo fast with heavier oils. Seems that 454 uses splash lube system for cam. Hence thinner oils keep it better lubricated.
Bob, Thanks for your input. The 454 I have runs well and want to get as many miles as possible before the dreaded rebuild. Slick 50 sounds like the best option so far. Thanks again.
Over on www.rv.net I read synthetic oil was OK but I have 92k miles and some concern on my 1992. I have not changed it yet by did get the WIX top of the line engine oil filter and the Pioneer (I think) transmission filter and gasket set. It takes 7 quarts with filter in my 1992. I have the GM shop manual that I picked up off of E-Bay.
When running a new engine one needs to first use a non synthetic oil untill the engine is broke in, then use the synthetic oil, you will create leaks in your engine. any filter can be found at napa just tell them what kind of truck you have.
