What’s the best type/brand of oil to put into my 1992 e320 coupe? I have a couple of packs of Mobil 1 in the garage – it this suitable or would I be better with a semi synthetic or mineral oil? The car has done 80k. I plan on keeping the car as its mint so would like to pamper it – the Mobil can go in my Ariel Atom.
Mobil 1 is very good oil and suitable for the car. I have however found issues with minor oil leaks -front crankshaft seal- when running a full synthetic 5-50. This problem disapppeared when I reverted to a semi-sythetic 10-40 shell helix.
I change it plus filter at 5,000 miles rather than the recommended 9,000. kinda depends on the use the car gets. LOTS of posts on the forum about this topic
Mobil Super S gets put in the S500 and the E280 i had previously.
I believe it's a semi synthetic oil, the garage I use swear by it and I remember them saying that a fully synthetic would be far too thin an oil for these older engines.
