I do extensive Blackstone UOA's. I used Red Line 5W40 for a few years with excellent results. Then switched to Mobil 5W50 (hard oil to find) for a couple years, again with excellent results, ever so slightly better than Red Line's.
Just today, I ordered Jake's Joe Gibbs DT40 5W40 oil. $153.55 case of 12 ($12.80/quart). Excited to try it. Will run it for about 2 years. Do mu UOA's and then decide if it is "better" than Mobil and Red Line. I am hoping it is. Charles and Jake say it will be. I trust them.
