| What is the best synthetic oil? Best oil filter?
I know that many here love Amsoil. I have used Royal Purple and it lasted longer and gave better mileage compared to other synthetics I've tried. Now Castrol has introduced their new Edge synthetic oil which they claim is the best. Does anyone know what oil is best according to independent lab tests?
Also what oil filter is best? I've heard that Amsoil, Mobil One and others have good ones that really extend the useable life of the oil.
Thanks in advance for any info. |
