Another analysis from Blackstone, and all good news. I am using the Lexus recommended OCI mainly because this is the wife's car, and in all likelihood, it will be sold, not kept like the IS and Supra. This history is worth far more than dealer maintenance records because it shows the wear on the engine over time. There is a long thread in the RC F forum regarding used oil analysis, which labs are best, which oils might (or might not) be best, etc, etc. I've made an active and informed decision to use one lab for all my testing and while they may not be perfect in many ways, they are reasonably consistent, and we honestly don't have control over the engine tune such that we can fix issues with fuel dilution or myriad other possible problems related to tune. So anyway, results are here.

 

Thanks for sharing, I ordered my kit today!

 

Thanks for posting/sharing Lance.

 

Update from the last oil change. This was the last run with Mobil 1 5w-30. It has been replaced by Renewable Lubricants 5w-30 Biosyn. While it is pricier than M1, it has significantly greater load capacity and fights fuel dilution well.

 

Lance,

Thanks for sharing. Is this what you're running?

Happy to see it exceeds Toyo's ILSAC GF-5 and API SN, and being partially recycled (bio) is also good for the environment. Might look into using it once my 10,15 and 20k services are done by Lexus.

 

That is what is in the car now. Time will tell how it tests when I send it in at the next change. My results above are from Mobil 1 5w-30.

 

Time for an update. This is the run with the Renewable Lubricants HDMO. Very hard to complain about results like this.

 

Those results are pretty much best case scenario! Are you happy enough with Renewable Lubricants to keep using it?

 

Thanks for sharing your results.

Steve

 

I am buying it in 5 gallon buckets now. Supra takes 6 quarts, and the two F cars are 9 quarts each give or take a little. 5 gallons goes surprisingly fast.

 

Great post, curious to see what Amsoil signature results would be

 

Latest update. Last load of RLI HDMO 5w-30. Really liking the bio oil wear numbers.

 

Learning curve for me has been steep since joining this forum but i am grateful for it. Thanks for posting!

 

Got the latest on the wife's ride. It continues to be impressive.

 

Looks good, thanks for sharing. Do you ever plan to run QSUD oil, given how affordable and easily accessible it is?
