Switching OILS

[MEDSTUDENT87]

I was wondering would you guys mind giving me your thoughts? I know there have been a million threads on oil and which one to use but I currently use mobil 1 15w-50 and run it for 10k cause I do 98% highway and long trips. I was gonna switch to Pennzoil Platinum 15w-50 and was wondering would brand change be bad? I know it is bad to take a car that has always used 10w-20 synthetic and use 15w-50 conventional but is it bad to change brands? The onl;y reason I am doing this is caues Mobil 1 sued Pennzoil over the use of fully synthetic on bottle labels. Mobil 1 lost the lawsuit and found out that pennzoil is a true synthetic where as Mobil 1 is not a full synthetic. SO pennzoil is tech. superior. THANX

If I am not mistaken, BMW suggest Mobil1 as the oil of choice. And no, switching brands is not bad if you're sticking with the same type of oil (conventional or synthetic).

Either way, don't worry about the engine ... if you change the timing belt every 50,000 miles, your m20 certainly shouldn't have a problem doing a million miles ... sounds like a cliche, but they really are bulletproof. As long as it has any kind of oil in it, and enough coolant, it will be a-ok.

Your sig makes me roffle.

M20's are rock solid. Use whatever oil you believe in, you will find 100 million answers as to what is best, just use what you believe in.

personally ithink using fully synth in older bms is a waste of money i used mobil 1 in my e34 but it made the cam followers very noisy ithink this was down to low viscosity of 15w on contacting bmw agent was told to use a good quality semi sinth and found this to be perfectly satisfactory.david u.k

Though it is an old thread but I want to correct this piece of information about the oil recommended by BMW …

BMW recommend Castrol & this is written in the BMW user manual of mt e39
