I was in advance auto parts earlier this week and the guy there told me he ran his oil for 100,000 miles, 13yrs on his toyota truck with filter changes + 1 quart every 10-15,000 miles. never cracked the drain plug, ever. I was like
but he says it was synthetic so it was OK and he sent in oil samples every filter change
(oil analysis is at least like $15, and he is already doing a filter change + 1 quart oil synthetic, why not just spend $5 more and get a jug of M1?) he went on for like 10 minutes, I feel dumber now, after hearing him talk.
This was the same place where a different employee told me Lucas Gear Oil >> Redline
quite a group they have working there
