So there's a sale at the auto store decided to try some oils (5w-30) labelled suitable for petrol and or diesel engine in my k24 and J35Z2 engine.
Bought some chief chicasaw and shell ultra full synthetic did oil change, fired up the engine oil exhaust stank bad hard to describe like rotten plastic burn. Once car warmed up smell disappears. Every morning I fire up the engine to work I would get that smell sometimes strong smell. I don't have oil leaks nor did i spill any oil anywhere to get heated.
Shell was in the J35Z2, there was a smell but not as bad as the chief chicasaw in the k24.
So after being fed up of the rotten burning plastic smell for about a month went to get some pennzoil platinum specific for gasoline engines only and put that in instead. Fired up the engine smell gone! I couldn't smell a thing.
(I went with pennzoil cause it was less then $47 for about 4.7L and claims it cleans better then mobil1 ep $65 and castrol edge ep $68)
Went and got FEO for the J35Z2 smell also went away.
Just wanted to say don't buy oil that's suitable for both petrol and diesel, but buy petrol specific only! Could be the extra cleaning additives for diesel engines causing the smell.
Before the suitable for petrol and or diesel engine oil change was using nulon and valvoline (on sale) had no smell as those oils were petrol specific.
So everyone beware of oil suitable for petrol and or diesel engine!
