engine oil

[roger bown]

what are the thoughts on engine oil ,should you stick to the sae40 as in the book .or use synthetic or semi synthetic

[JulianS]

I use Morris 20/50 in my A10 and have done for years. No problems found.

There are many varied opinions on oils.

As per my earlier post on Oil Pressure. I use straight grade 50 without problems. As long as there is plenty of oil in the tank and its clean then the engine will be fine.

Hi Roger,
              If you want to make your own decision, this book is a good read:

If you don't want to spend the cash, here's a free short condensed outline of which oil to use:
