God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Oil

Hello everyone. I'm new to the forum and have a quick question.

Basically, is it safe to put synthetic oil in a high mileage engine?

My car has 300k.

Depends what weight it is and if It's right for your climate otherwise there's no problem using synthetic oil. But I would stick to good old dino oil if you can. It's much cheaper and there's no need to use synthetic on high mileage cars.

you can cause oil leaks. synthetics clean the engines really good. so if you have some carbon gunk keeping a gasket sealed, synthetic will pull it out and cause an oil leak.

I would suggest not too. Castol gtx has a high mileage semi-synthetic that I ran in my E30 and made it run a little smoother and may have helped with the oil leak it had.

+1 on Tkaczuk. A Castrol lecture I attended advised use only oil available at the time of an engine's manufacture. That is what it was designed to run on.

My friend said the same thing. I think same weight in other oils would be okay but more specifically moble 1 would run about the same. I haven't used to many other oils. Royal Purple went in my 24v swap.

I have often wondered why some people put synthetic oil into their banger ?
There is a oil for every aplication & just because you abused your baby in the past, expensive oil will not make her love you again
Synthetics are great for high rpm, high heat applications Oh yes, before I forget, they look good in the ads too
I believe in spending my money wisely i.e. Value for money...
So before I spend money on a Lubricant I don't need I will maybe flush that LSD with new oil or the radiator, or maybe even flush the dark juie that started life as hydraulic fluid in your break & clutch system....
