Buster,

Posted UOAs in the infamous engine can show 7fe or as posted a 17fe compared to av of 12fe - ? what is conclusion

An engine is recommende a 40 in europe but 20 US if a 0W40 shears is this an issue?

If high heat from ambient or use should visc be reduced or increased.

With cold starts and short trips do you want thinner oils and perhaps esters?

Doug posted "there are no magic oils" but expressed a view based on vast experience.

In the UK Castrol and M1 are described as "shed oils" but cost is a driving factor!

What is obvious is when push comes to shove a number of experts are silent, perhaps censorship rules!
