FAO Mr Oil man....
Discussion
Pwig,
Is this your new purchase??
Originally your car was recomended a 15w-40 mineral oil
but that was then as the engine dates back a lot further then the car.
You can use, 10w-40 semi syntehtic and if the car is well maintained then you will have no problems moving to 5w-40 full synthetic.
I personally would only go for a BMW approved one.
Have a look on my site here www.opieoils.co.uk/lubricants.htm
And have a look at all the options, steer clear of home brands and if you would like a price list drop me a mail through my profile.
Hope this helps.
Cheers
Guy.

And me: What oil should I use in my 5.7 Litre chevy engine, thats having a pair of turbos fitted to it?

Eliot,
For this I would only recomend the Silkolene Pro R 15w-50, this is an ester/pao synthetic and has been well proven in the American V8's.
It is good value for money, and having a a pair of turbos fitted you really dont want to skimp on quality so doing you best to keep it tip top.

Mr oilman 
Is it wise to switch an old engine from mineral to synthetic oils?
I only ask because certain manufactures state that their engines have been designed and tested to run on semi synthetic's and the use of fully synth's can cause degradation of the seal materials over time.
whats your take on it?

What would be best for a Lexus/Toyota 1uzfe V8, which is going to have a twinscrew/Lyshome blower stuck on it?

Pete,
The standard recomended grades for the Lexus V8's is 5w-30 or 5w-40 depending on madel and age, can you tell me a bit more about it.

Nowadays this tends to be an old waives tale as synthetics have moved on a long way since these problems were encountered.
What car is it??

Most engines are tested on semi or mineral oils, especially jap engines, this is for several reasons and the main one being cost, to both the end user and themselves.
When they manufacture a car, they have to declare what they think the running cost of the car are going to be throughout its life time, they count mineral based oils for this as they are cheaper, so if you want to buy a second hand zetec fiesta as a run around, its cheap realiable full service history you name it, would you still be interested if every time you wanted to change the oil it was going to cost you £50 instead of £10 as you can only use syntheitcs as that is what the car was tested on during design?? the answer is probably no, and the manufacturers know it, they save the synthetic only behaviour for the likes of new Porsches and BMW's that sort of thing.
They also test and recomend synthetics as a minimum spec to be used, at times you may not have access to or funds to buy true synthetics, so the minerals can be used.
However those days are comming to an end, thanks to mpg and emmision regulations calling for low energy synthetics, the VAG group is already going down this road.
