What is the best synthetic oil? Best oil filter?

Vdrenaline · #1 (**permalink**) 03-08-09, 02:20 PM

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.

"Best" is always subjective.

Personally, I run Redline in my Trans-Am, Mobil 1 in my motorcycle (motorcycle-specific, not standard 10w-40), and K&N filters in everything.

Everyone among the LSx crowd has their favorites. Castrol German 0w-40, Mobil 1, Royal Purple, and Amsoil are among the popular choices. I don't think you can go wrong with any of them personally.

Amsoil has produced the best results for me. 20,000 miles between changes and 2-5 mpg improvements to boot.

Thanks for your reply CSX. I was hoping to eliminate the subjective by trying to find independent lab tests demonstrating which one is best. Castrol Edge claims that independent lab tests put it 8 times better tham Mobil One but I'm not certain how "Independent" their tests are.

I also heard that 1-2 years ago, Mobil One changed their formula to use cheaper base materials including cracked carbon which is not as good as their original formula.

My own personal experience has been that Royal Purple is great but I've never tried Amsoil. I am about to try Castrol Edge for the first time.

Thanks in advance to anyone who can point us to good, independent data to help us make good choices on oil.

Are you on LS1tech by any chance? Patman, who frequents there, is a hardcore oil nut, and has more knowledge on this subject than probably anyone on that site. He has access to a number of independent tests, if I recall correctly.

I am going to run strictly Amsoil 0w30 Signature Series Synthetic Motor Oil and the Amsoil EA oil filter. Which other oil guarantees protection for up to 35,000 miles in normal driving conditions? Amsoil seems to be the only one.

Amsoil is 10 years ahead of everyone else in lubricant technology.

I have used Red-Line, Royal Purple and probably most of the synthetics on the market and based on the research and testing results I have seen, Amsoil always comes out on top.

+1 on Amsoil. I just replaced my oil yesterday at 1509 miles.
