Thinking about switching to Mobil 1 10w30 HM in my 96 Mark VIII which has just over 100,000 miles. Reason why is it's really cheap at Wal Mart compared to me ordering Amsoil ASM 0w-20. What do you guys think?
I ran regular Mobil 1 10w30 in my 94 Mark VIII until 160,000 miles. Until I sold the car. No wear aver shown in any of the used oil analysis and a 8000 mile OCI. Regular M1 is fine. HM won't hurt. I would not weat it.
