Its a BMW E36 with a M50 engine. With the Mobil 1, during cold starts and short city trips the engine is smooth but once its driven hard, the lifters and vanos are clearly audible. Have heard that the Mobil 1 has shearing issues.....
On mineral oil (I usually use HDEOs ), the engine purrs. Wanted to try out synthetics for better protection and longer oil change intervals.
Do you know of any reputable brand 20w50 full synthetic being sold in Khi?
