Hi Forum,
Just sold my 96 LS 400 w/ 207K miles and bought a 2002 LS 430 w/ 76K miles. The 430 is a family car, never seen a winter road yet, and been almost exclusively dealer maintained except for oil changes. Has had a combination of Castrol Synthetic Blend & conventional oil changes every 3K miles.
Questions:
1) Has anyone used AMSOIL Motor oil? Is it really as good as they say it is? Can you go 25K miles between changes w/ a AMSOIL filter?
2) My LS 430 has no oil leaks now. Should I be concerened about switching over to a 100% Synthetic oil?
3) I usually have Jiffy Lube change my oil, but I just don't trust them, too much employee turnover, and too many scandals. Does anyone know any shops in Massachusetts where I can get an AMSOIL flush & oil changeover done?
4) What about AMSOIL air filters, they are guaranteed for 100K miles if you clean them every 25K miles. This seems a little extreme!
Thanks,
NausetDog
