Caterham dont quite understand what you mean. I completely agree that Redline is tops as far as 20weights and is actually what i used to backup my factory fill oil. However since I dont tend to read up much on the Mobil 1 threads around here I was looking for a little help as far as a possibly a 'best value' in the Mobil 1 20 weights.
cheers
To me "stout" refers to either a VERY high ppm content AW add pack (like the M1 High Mileage oil lineup in the Mobil brand), or a VERY high detergent/dispersant, high TBN retention, add pack (like the Mobil 1 Extended Performance oil lineup in the Mobil brand, although some claim that EOM uses a different base stock type as well to give this stuff it's long drain capabilities), or BOTH as in many top-drawer 'boutique' oils.
As far as I'm concerned 'stout' has NOTHING to do with HTHSV, or KVs @40*C, or 100*C, although the amount of, and type/quality of VIIs, and how resistant they are to shearing, DOES have a bearing on an oil's "stoutness" (to ME at least).
