If that rig had a 1000 series Allison, they'd eventually scrap the truck and put the trans in something else.

Wonder how the oil pressure compared to running on 100% oil?

Makes sense especially if the internal converter seals are a bit worn and the top half of the converter drains back easily to the sump after shutdown. So on startup you have a usable oil level but quickly pump the converter full pulling a couple quarts out of the sump and then have low fluid...

I'm curious what your oil temps are in those. I checked my 20hp Kawasaki / Tuff Torq hydro (John Deere chassis) after mowing one hour in 90 degree weather and was surprised how low the temps were, engine oil 170F on the pan, Hydrostatic trans was 150F. Convinced me those applications aren't...

Most of it is pure profit. Selling boutique oil products is highly profitable. One look at Forrest Lucas's mansion here in Indianapolis (that he doesn't even live in much of the year) tells you that. https://www.omnihomeideas.com/design/celebrity-homes/forrest-lucas-house-in-carmel/

I'm not sure what brands Gibbs used prior to Driven. They said Driven was developed because the available oils were causing engine failures (Nascar Cup series at that time was running 9000 rpm with flat tappet cams and very high valve spring pressures. Cam, lifter, and valve spring failures...

Back in the day (1960s) at Chevy Tonawanda engine they did the initial run-in ("hot test") at the engine plant on gaseous propane. They didn't put a carb on the engine until the assembly plant. The old joke was take it right up to 5000 rpm and if nothing comes flying out, ship it! The...

Indycar which I'm more familiar with on the tech side verifies that sponsored products are actually used, although it's not at the molecular analysis level. Is Nascar similar?

So those Valvoline decals on the Hendrick cars are just for show? Penske Pennzoil is just advertising but not actual product? Quaker State on Trackhouse? I thought Nascar verified that the teams were using the actual products?

This sparked a couple other questions: Did Lake Speed leave the Joe Gibbs Driven lubes program when Gibbs spun it off to whoever owns it now? Did Gibbs Racing switch to Mobil because Toyota wanted that, or was it was better financially to have Mobil as a sponsor than to compete with them...

Is he actually selling a product in these? I've not paid much attention. Or does a YT with 62,000 subs generate much income?

Slightly off topic but I think with modern electronic brake control systems, they can modulate to make the rears work harder for anti-dive without worrying about rear wheel lockup in slippery conditions. On my 04 Cadillac the rears wore out before the fronts.

That's interesting. I have an old Saturn with an Aisin AF automatic transmission that has a "don't remove this unless you're rebuilding the unit because unscrewing it will allow an internal part to disengage". Wisely they put a 5-sided head on the screw in fastener.

Do you change the oil while you're in the US and smuggle it back in that way? 😎

On the 2019 Blazer I had, the 2.0l turbo 4cyl spec'd 0W20, the 2.5l NA 4 cyl was 5W20 and the 3.6l NAV6 was 5W30.

Does it come in discreet packaging?

If you're going to Menards anyway, you can buy almost anything there these days. The selection of packaged grocery items seems to grow every month which is interesting to me because I hardly see anybody buying groceries at Menards.

How your neighbor views your motor oil as you're pouring it in: Mobil 1: Our dentist uses that stuff in his Porsche. Impressive! Kirkland: Value with a touch of style. Bet he grabbed the $5 rotisserie chicken too. Supertech: That motor's gonna puke before he gets two blocks down the street.

THIS is awesome! Thanks for sharing LOL.

There's a big difference between increased wear rates discerned from oil samples, and actual increased engine functional failures. That's what I was referring to. Big picture data on vehicles tells us at least in the US, vehicles are running longer than ever so the combination of lubes...
