This is a great report. How long have you been running Redline? What other oils have you used?

 

[MB289]

Sorry about the lack of background, but I lost my first report and just put the results.

I've been using RL for about the past 35K miles. I got the car with 35K, and at the time it was using about 1qt per 5k miles on M1 10w-30. After switching to RL, over time, the oil consumption is way down. About 1/4qt per 6k miles. I'm no expert, but I think it's due to RLs ester base and keeping the ring pack clean. Keep in mind the car is my daily driver and is not driven hard and most of the miles are from my round trip to and from work of about 40 miles.

The only thing that concerns me is the high silicon. It's about the same as my last UOA, only done yearly. I've been over every inch of the intake and have found no leak. I do run an after market lid with a paper fram filter.

high SI maybe antifoam in the New oil if you had ran a baseline VOA on the batch you have that would tell you since you did not do not worry about it, it is not to bad.

RL shines copper. I mean yes GM's throw Cu....but....decent report. Some Si is native - but still triple check the engine breathing and intake.

This VOA of Redline 10W40 shows 14 ppm of silicon. So it's likely that the Si was in the oil to begin with. Got some virgin sodium in there as well. So I wouldn't worry about your numbers...

Flash Point is low. Not sure if that means anything.

Results are excellent...I'd step out to a 9000 mile service interval based on this data.

Doesn't that mean there is a fuel dilution problem on an ongoing basis that just isn't in this sample?

 

[SSDude]

This report is excellent. Too many people give up on Redline too soon because of its initial cleaning.

 

[Patman]

Results are very good here and I think Bruce is right, the silicon is antifoam from the oil itself, so only about half of that number might be actual dirt. Based on the low engine wear, I would not worry unless that silicon number goes a lot higher in subsequent reports.

so much old data on this site. Here is a very good report of someone that ran RL 35k miles, and notice the wear metals are very low after subsequent RL intervals. Haven't seen many cases of this.
