Re: synthetic vs nonsyn. motor oil
j_martin... question for you.
If you run synthetic oil for longer periods and change your filter every 3k miles, how long do you run the synthetic oil before you dump it?
Hey, I?m with you on that. My Mercedes manual recommends 0w-30 Mobile 1 synthetic. Specs, say to change filter and oil every 10k miles. It KILLS me to see how clean that oil is every time I dump it. So, I?ve started changing the filter every 5k miles and changing the oil every 15k miles. I thought I was stretching it until a friend told me about the Amsoil he uses. My friend said he changes no less than every 25k miles and he has gone farther than that after sending a sample of his oil off for testing. He did admit that he changes his filter every 10k ? 12k miles though.
Does anyone else maximize their synthetic oil like this?
