But hey, you seem to have already talked yourself in sticking with conventional. So enjoy and hope it works out well for you.
But hey- you're funny.
I don't see how you assume I talked myself into using conventional. I simply asked a question. And what ppl thought of the Blackstone assertion. I use synthetic. It seems you are making claims about synthetic and talked yourself into using it. The Blackstone guy is basing his opinion on the results of 10000's of oil analyses while you just have an opinion.
There once was a GM powertrain engineer that(banned on this forum) was very familiar with lubrication of high performance engines. He claimed synthetic was really only necessary if oil temp exceeded 305f or for cold starting.
Now go and check out the latest oil bottles at WM
My Dad was a GM engineer for 45 years.....in manufacturing for turbine engines and transmissions, at Allison Gas Turbine, and Allison Transmission. He had a different opinion and ran Mobil 1 in his cars and trucks. He knew and worked directly with chemical engineers from Exxon Mobil, among others. That said, he would have also told you there is nothing wrong with a good major brand conventional oil. He ran synthetic because it simply performed better, and cleaner, in extremes. There are places in the engine that can get to extreme temperatures. That's where sludge is more likely to begin. He went synthetic because it was much less likely to break down or sludge, and he kept his cars for a long time. There was a time when he didn't keep them more than a year or two. He used the cheapest oil that met spec in those. Usually Valvoline white bottle or PYB.
I'd bet most powertrain engineers that are gearheads run full synthetic. I'd be shocked to hear otherwise. That said, I think today's conventional oils probably have a good deal of group III in them, to meet more demanding specs, so they probably perform very well.
