Here goes, I am confused and need some advice from this forum experts
.
I have year 2000 Lexus ES300 sedan and own since new and change oil every 5k miles. At 90k miles, I switched to Castrol high mileage and I am on 151k miles now. I don't have any burn-ins or leaks.
However, I happen to see Mobil 1 high mileage synthetic oil at Walmart and thinking of switching to it. My questions are (if cost is not an issue):
How is M1 compare to Castrol that I am using?
Will there be any advantage to start using M1?
I read on this forum that regular M1 synthetic oil shows high iron wear on UOA testing. Will that be true with high mileage synthetic as well?. I use purolator one oil filter.
Appreciate your valuable inputs......
