Yep … ATF is not just for a single purpose … but it’s not cheap either …The fascination with ATF...when there are actual products for this. Mind blowing.

Having a clean car, a clean engine bay, fluids full, and all your receipts + spreadsheet etc. should basically eliminate the drama with "this oil you have been using isn't approved" but of course there are always exceptions etc. making this convo pointless. You are always safe following the vehicle manufacturers recommendations/approvals.I take what I've seen working at different dealerships, and from friends that still work at dealerships to be reliable sources and information which I believe. Some here might call it anecdotal, I can't change that. Warranty claims can be denied and have been denied. It is a rare occurrence but it can and does happen. If it does it often ends up in court.
I can say this, the odds of having a claim denied can be reduced by having the proper fluid level in the system in question. Eg: engine knock, make sure the oil level is full before bringing in the car, transmission issue, make sure the fluid level is correct. Clean cars seem to be thought of as better maintained by some people too, even though that isn't always the case. In the unlikely instance of having a warranty issue knowing what to say and what not to say helps too.

Highly doubt that is an issue. Most of those cars are dry sump and the average guacamole at Jiffy Lube is going to turn them away based on insurance risk alone let alone figuring out pulling 3+ drain bolts and oil lines. Professional shop will use what is appropriate or be held liable.What about in super exotic cars?
Your conclusions are opposite of what most/many/I think. Going thicker than the recommended viscosity, within reason, is never a problem but going thinner very well may be a problem.I can't imagine why anyone would even attempt such a thing. The way these engineers design these new engines, with such tight tolerances, a person would have to be out of their minds to run ANYTHING but 0W-16 in a new Toyota. It's why they place half a dozen stickers all over the engine bay telling you as much.
Anyone who knows anything would surely realize that it would be futile to do so, because the engine would seize into one solid mass before you got 3 blocks down the street.
Now, if you ran 0W-8 I might see some benefit. But ONLY in ambient temperatures above 100 F, and if the engine was going to be run at 6,000 RPM for hours on end, while towing 25,000 lbs. or more.
I’m gonna go out on a thick limb and say this is 100% urban myth since right in Subaru owner manuals it says something similar to “elevated temperatures or sustained high-speed operation may require thicker oils for sufficient engine protection”.I’ve “heard” of Subaru denying warranty due to using 5w40 and not 5w30 but since I don’t actually know of someone personally having this happen I am not sure if it’s real or not.
Straight from my Tundra owner's manual (says the same thing in my wife's Lexus manual):I’m gonna go out on a thick limb and say this is 100% urban myth since right in Subaru owner manuals it says something similar to “elevated temperatures or sustained high-speed operation may require thicker oils for sufficient engine protection”.
I was being sarcastic.Your conclusions are opposite of what most/many/I think. Going thicker than the recommended viscosity, within reason, is never a problem but going thinner very well may be a problem.
Really??? He didn't even have to bait the hook, cast the line or anything. You just jumped in the cooler.Your conclusions are opposite of what most/many/I think. Going thicker than the recommended viscosity, within reason, is never a problem but going thinner very well may be a problem.
Reading this, I was thinking.....NOOOOO WAY ANYONE IS GOING TO FALL FOR THIS.I can't imagine why anyone would even attempt such a thing.
