Switching from 0w-20 to 0w-30 experience

[GW.]

I came across this video a couple of days ago. Apparently, he is using 0W-20 from the dealership, at 10K mi OCIs. Obviously severe duty operations with offroading and long idling, which even the manual advises going up in viscosity and cutting down the OCI. Yet, it lasted 250k miles. Maybe someone could shed a light about if the failure was potentially caused by not changing from the "normal" OCI/grade. Details about the issue at around the 22:20 mark.

First step would be a complete disassembly to diagnose the loss of compression. I wish we could see the inside of that engine!!

Back when I worked for the railroad we had some 4runners used by ECI foreman. Those had 400k+ miles of hard use on them.

True, all things being equal - and real world city driving cannot provide this ... so, any huge change (like 10%) is simply because the real world city driving differences caused it. "I am not in a controlled environment ..." - exactly.

A controlled environment test will not change by 10% ... 0.5-2.0% is sort of the accepted range with minor change from branded synthetic 0W-20 to branded synthetic 0W-30 - that's a reasonable range to see differences.

Exactly the issue and somehow it seems difficult to comprehend.

As you note, in a controlled environment where the oil is the only variable the difference in fuel consumption between grades is about 1% to 2% maximum. Grades are grades, so it depends on the specific oils under test.

Not disagreeing, however in the case of business it matters greatly. The difference in fuel cost might seem small though it adds up. In my case 7.50 a week savings. Only use Exxon gas and Valvoline oil. Anything that can be done within reason is how you survive.

C'mon, shilling for companies? Really?

$30 could be a water or home gas bill.

Calling someone a shill just for sticking to Exxon and Valvoline is crazy. $7.50 a week might not sound like much to some, but over a year that’s nearly $400 in your pocket. Small savings definitely add up when you drive a lot

I have been running Mobil 1 5w/30 in the '14 Grand Cherokee Overland since new (now has 201k) and the '20 Gladiator (now at 88k). I feel 30wt is the best oil to feed the 3.6L. I have run AFE 0w/30 once or twice when I had it on hand. Bottom line, be it 0W or 5W - make it a 30wt.

Without evidence that those two companies' products make a difference? Or, maybe because Dad only used Exxon gas and Valvoline oil?

I think members here best stop being so opinionated on others opinions and quit chewing one another out. Bad for the BITOG moral and makes quick for the down.

My uncle would remind everyone, "Those are after tax dollars".

This is generally a science and (near) fact-based site ... feelings on oil don't help much.

Yes, like I’ve said if fuel economy is your one and sole concern then that’s the reason to use lower-grade oils.

Don’t know if those helped, however that’s what I run. This was stated as everything I do is routine.
Exxon gives me 20 cents off then upside gives 10 after so many tanks of fuel. I’m a believer in Valvoline is why I use it in everything.
No Dad ran only Shell and Pennzoil

This is your opinion.

If we are talking about the multiple studies @kschachn mentions, it's not really opinion, but generally accepted fact. However, just because it's measurable doesn't make it meaningful. This is precisely what Honda was talking about with respect to "acceptable wear" when they were doing their thinner oil testing.
