better wear numbers with conventional oils than synthetics?
Really? So, Why do we use synthetics? How can they sell synthetics? I believe most of ours OCI is 5k-7.5k. Most new vehicles have 5k or more OCI requirment by factory.

---

Synthetics are supposed to last longer than conventionals; allowing people like JAG and Buster (whom do not like changing oil) to go farther on an OCI without having to change their oil out. You could maybe change a conventional twice as often and have no more wear than a synthetic changed half as often.

like i said before in my tacoma that i ran M1 syn 5w30 for over 40k miles deff had motor noises like ticking and etc.. since i switched to durablend 10w30 the noises are gone and my idleing is smoother. ill check back on these after another 1000 miles or so.. so far, i like the durablend.. next ill try PP or valvoline syn

The filter theory is interesting. Many folks using M1 are often using the M1 filter which is known for being restrictive.

Mike, how's that Durablend 10W-30 working out for you?

PAO is not a very good lubricant... Especially at lower temps. PAO's only benefit is at extreme cold and hot temps (flow/oxidation stability) where a hindered ester would be a better lubricant than PAO.
