Help me! Engine oil problem!!

You are deeply mistaken. I will agree with you that RP is not the best 'bang for buck,' so to speak, but if you're willing to fork over the extra Benjamins, you're in for one of the highest quality lubricants in the market.

I then found the average for each wear metal (iron, copper, etc..) for all the UOA results and the standard deviation of each wear metal result from the average. This chart shows the average wear for each current oil tested in terms of ppm/1000 miles. The cells with a green background are better than one standard deviation from the average. The cells with a red background are worse than one standard deviation from the average. The average and SD, remember, is calculated from ALL the samples I have from the VQ. The average wear characteristics of some oils used in the VQ which are no longer in production I have also included in a separate table.

The interesting thing is to note which oils are statistically significant in terms of better or worse wear from the universal average for each wear metal. It would be nice to have multiple samples from some of these oils before the manufacturer changes formulas again.

Castrol Syntec 0W-30/5W-30 did good from that chart

NIZMOZ · 05-27-2009, 03:27 PM

Castrol makes good quality oils. Especially the German Castrol.
