There are a billion threads on which motor oil to use and why; just do a search. Here, and also at bimmerforums.comscott41258 said:any recommendations/opinions on whether i should use regular motor or synthetic. my 328i has 114,000 miles.
If your car has been on regular hydrocarbon oil then stay with it or use a blend. If you switch over to pure synthetics, you might get some leaks from the gaskets.scott41258 said:any recommendations/opinions on whether i should use regular motor or synthetic. my 328i has 114,000 miles.
Since when is 114K miles high?ImperialDuckM3 said:Scott, since your car is high milage. I would recommend that you stick with standard graded oil 10/30 or 10/40. Going full synthetic might cause oil to slip pass your rings and gasket (aka oil leak). But if you own the car since day one and been using synthetic, then just stick with synthetic.
It doesn't matter if its a 86 Chevy with a 350 iron cast block. With heat and temperture, it will affect the engine (hence wear and tear). Yes the dealer use synthetic and that point is very clear.bol said:We're not talking about an '86 Chevy with a 350 here. '96 isn't that old and 114k miles isn't 'OMG HIGH MILEAGE' Chances are it's been serviced at the dealer and guess what? The dealer uses synthetic(and have for many years!) Gasket swelling isn't a big issue any more. It's not like synthetic oil is new. I'm not going to argue, there are enough topics on the internet about engine oil to make somebodys head spin. You're just adding panic and fear to somebody who is looking for an alternative.
Don't assume anything about me. I didn't assume anything about you.
