Originally posted by icruse: Do not know if it has been mentioned yet but Mobil 1 has put up a whole new set of Tech Data sheets. Some different numbers to.

There will always be slight variances to these numbers. BTW, I still don't see specs. being as vital as previously thought. When you look at all the analsyis comparing M1 to oils with higher specs, it made NO difference. [ April 05, 2003, 11:58 AM: Message edited by: buster ]
The numbers listed for the oils are all within typical mfg variance of the previous specs
quote:The other M1 grades are stated to be synthesised hydrocarbons. Had a former castrol tech tell me that M1 5W-50 was going hydrocracked, but paid little regard to it. Still the statement on it's own doesn't mean much.
