Ok...so I'm bored at work and it humors me when motor oil web sites try to recomend an oil for you, so I was on Valvolines site and they chose Maxlife Full Syn for my van with 85k. Then they listed all the other ones they had and you could click on it and they would tell you why they dont recommend that oil for you vehicle. So I clicked on the Synpower and it said the followoing:
SynPower
Because your engine has over 75,000 miles, we did not recommend SynPower®. SynPower Full Synthetic motor oil delivers superior engine protection by fighting the 3 major causes of engine stress: heat, deposits and wear. SynPower delivers outstanding protection in extreme temperatures, superior cold start properties and superior deposit control, but it does not have MaxLife’s added ingredients that are designed to help fight the aging of critical engine parts.
The last line is what really got me, because isn't synthetic going to do just that? Fight the aging of engine parts?
