So what are the gains to using the blends offered by Honda, Toyota etc. over the full synthetics like Mobil 1 and others are advertised as? Knowing M1 isn't a true synthetic of course, but still.
It's up to you and your car's lifestyle.
I am Mr. Honda. Welcome!
I use 5w20 PP in my CR-V which now has 210,000 in it. It really didn't like M1 EP when I put that in at 187k. It leaked and burned. It has since fixed itself regarding those issues since I put the PP back in. This car is mostly highway and has been since day 1. To be fair, I've done 2 UOA's on it and I ran this oil for 13k. Flawless. PM me for the report. I usually go 10k on PP.
I run M1 0w20 in my 2008 Pilot exclusively because the wife drives about 5 feet (exaggeration) and shuts it off. I need the "cold" protection for this reason. Zero issues. I run this oil until the MM says 5%.
Your proverbial mileage and experiences may vary.
As they say on this board
I cant think of any advantages of using a blend over a synthetic. The only reason I used the Honda Blend 0w20 for my last OCI was because I got all 5 quarts shipped to my door for under $10 on Amazon, now they are $13 per quart. Keep using the M1 and Fram Ultra, exact same combo that I have on my Accord now. Runs great on this combo. Might have a winner!

As far as I am concerned, M1 is a synthetic oil. As is PP, PU, Castrol Edge etc.
I use syn blend sometimes on my high mileage vehicles that i use high mileage oil in the summer and syn blend in the winter pennzoil says its syn blend is at least 50% synthetic. (synthetic is a tricky word) But i believe its good oil anyway.
On my other cars i use our bulk which is now gulf i think
many oils are "synthetic" only in USA, technically i like to say group III oils. yes they are quite good for a highly purified dirty petroleum product. since the word "propriety" where manufacturers hide info so we can't compare we really do not know whats used in them. some group IV PAO or group V oil may be necessary to meet the 0W spec. some specs can be "propped up" with cheap short lived additives as well. a low pour point for instance should have a good HTHS otherwise its prolly "propped up" comparing to Amsoil specs for their top line PAO group IV oils is a good guideline IMO
You sure know a lot about severe hydrocracking, where did you learn so much?
