Just wondering, what's the general opinion on Valvoline MaxLife versus Castrol High Mileage?
I've done a few searches on the topic here, but I have turned up empty. There are tons of topics on it, but none of them seem to have any real facts or supporting evidence- merely product bashing or some sort of glittery generality.
The closest I have turned up with is one anecdote of Castrol High Mileage stopping an oil leak with Valvoline MaxLife failing to do so (however it was uncontrolled as almost all anecdotes are and the Castrol was pushed only after having used MaxLife twice, which could be nothing more than an adding effect). Furthermore, the only other information I have gained is that the Castrol High Mileage tends to be on the outer extreme of viscosity at 30 which could also explain why that particular leak stopped. I'm a thin oil guy myself.
So what're your thoughts (and please provide reasoning).
Thank you,
Techniker
