I was speaking w/a friend about synthetic oil. He mentioned TriboDyn blue (ya,it’s blue) synthetic oil. The specs look really good. Better than Amsoil! The bad news is it’s about $19/quart!!!
He also mentioned that the low weight oils are primarily for gas mileage?
I never did like the oil pressure at 20 or slightly less at idle!! I would much prefer 35 at idle. Maybe I’m too old school?
Anyway has anyone used this stuff and how do y’all feel about the recommended oil weights on C6’s or other late motors?

No, not heard of it before your posting. I did take a look at their website. I didn't see anything unique other than "blue," and the price. Originally the lower vis grades were primarily focused on MPG but not so today. Engines are designed specifically for the vis grade specified by the manufacturer. Variable valve timing would be an example. I would recommend that you save your money and chose either Valvoline SynPower or Mobil 1. Personally, I'll continue to use Valvoline products. Too much hands-on knowledge in the Valvoline Technology Department for me to do otherwise.

Thx for ur input hadn’t thought about Valvoline

R&L's C6

I also use Mobil 1 or Valvoline.

No need to reinvent the wheel, at three times the cost no less. JMO

Ya. I thought it was way too pricey short of having discovered some wild breakthrough 😏

Along with the "standard" color...(if you will)....there seems to be blue....red....purple....and probably a couple more that i've missed. It could just boil down to what color one likes best.....

Dynajim

My wife would like pink😏 I better not tell her

Help me out here...Valvoline has more "hands-on knowledge" then, I assume, Mobil? Please help me understand...

Not sure about Mobil. I was referring my personal experience at Valvoline. Forty years in the Technology Department. I retired 4 years ago.
Just a couple of pieces of Valvoline history:
The world's oldest oil company, founded in 1866 by Dr. John Ellis.
Many technological developments over the last 150+ years. In 1965, we undertook the development of Valvoline Racing Oil. The first engine oil formulated specially for racing. A really neat project that was conducted in cooperation with Porsche.

The primary spec for oil weight is bearing clearances.

I wouldn't pay that kind of price when almost any mainstream synthetic oil will serve the purpose when you change the oil and filter at regular intervals. I typically use Pennzoil Platinum based on very good long term UOA results on wear resistance and resistance to shearing in DI engines. If it's out of stock at Wally World when I go, I will purchase Valvoline, Castrol, Mobil, or Quaker State full synthetics. I change my oil and filter at 5-7k mile intervals, typically at the 5k mark, so any good synthetic works for me.

But not sure what all the techno wording means...LOL. I too just use a supposed "Quality" syn when I change. Been doing this with all my cars forever and have never had an oil related problem. Of course before the forum trolls come out....yes years ago syn wasn't available so any good quality dino worked for me. These days I use syn in the vette & Harley and blended in all other cars. But if it were up to a color choice....I think i'd have to go with the purple stuff.....

Yes, I built some engines. In "old school" vernacular, we sometimes would build "loose" engines (larger bearing tolerances). We couldn't use low viscosity oil. Never get or maintain oil pressure. On the other hand, if tolerances are really tight, a low viscosity oil is needed or lubrication would be poor to nil.


Secondary to this is ambient air temps etc., and after that, improved mileage with certain viscosities, but the improvement is 0.xxxxxxxxx. But, times tens of millions of applications.....
