Like an idiot I trusted Mr. Lube to give me accurate info on my oil change - you'd think they know. Well, I was told I definitely had synthetic oil in my 97 528i and I went with their recommendation of Castrol 15-40 synthetic. Of course, after the change I discovered the original oil was not synthetic - am I going to regret this change over; the car has approximately 80,000 miles on it.

I won't worry about it..your engine is not that fragile! simply change it with the recommended oil.....I use 5W-30 BMW synthetic oil...works just fine ....

Once I used Mr. Lube's service their tech broke the drain plug in half . Tech was not aware of the fact these plugs are hollow metals! Say it with me....never again.....

Let me know how that works out. I've got a 97 528i with 89,000. I've been wrestling with the idea of going ahead and putting synthetic in it (5W-30). Haven't done it yet as the car has always had regular oil, but keep thinking that I might want to. Like you, I'm worried it may expose leaks and such, but the car is in such good shape, I keep thinking it will help ensure my engine lasts for a long, long time.

Well, I'm toying with sending the local Mr. Lube a registered letter saying something like this: "On radio ads, you claim to be the fluid experts. Since you maintained your expertise in oil changes, I naturally took your advise as to which oil to place in my BMW 1997 E39 528i. It turns out your expertise may be flawed as I was advised at Mr. Lube that the original oil in the Bimmer was synthetic. I have subsequently found out this is not to be the case. I will be holding you financially responsible for any subsequent leaks resulting from an oil substitution of synthetic oil from regular oil."

I have seen other posts on this and other Bimmer forums of guys switching and not having any consequences on older cars. And there is one nut case here locally who does a 50/50 regular/synthetic insisting this is the best oil choice of all. So far, his car is still running just fine.

I thought synthetic was good all around. Even changing from regular oil. Though now I recall when I did switch from regular to synthetic in my old VW 95 PAssat, I had oil leak problems. About $1500 later the oil problems ceased, but the engine ran like new.
