Mobil 1 advanced vs Mobil 1 extended

I used to think that regular “vanilla” M1 was good enough, especially for people doing 5k intervals, and in the past it probably was (especially in the “tri synthetic” era) But now I’m rethinking that when I hear of people that are switching from regular M1 to VRP and finding that it is doing some cleaning, as well as reducing consumption. So it appears that the basic M1 might not be the way to go these days and you might have better results using M1 EP or ESP or any of their higher end offerings that have more stringent approvals. Just having dexos1 approval doesn’t seem to be enough these days.
I wouldn't believe everything you hear.
 
The way I look at things like that is - the newer and more valuable car/truck/item is worth better care that may result in higher maintenance cost; to me a better oil is justified. Better care will result in longer life and better condition of the item over time, in case the owner cares about such things. In short, I'd rather use better and more expensive oil on a newer vehicle than on a (non collector item) 15 year old one.

I think he wasn't trying to trash vanilla m1, more so explain that there are oils out there that can remove some of the markings of older oil. I consider EP M1 night and day ahead of its other products minus maybe the 0w-40. To be fair most premium lines of oil do a much better job. Pennzoil Ultra Platinum was proven to do so over Platinum and im sure Valvoline Restore and Protect and Extended Performance High Mileage beat the pants off the lower tiers. Amsoil SS would be the only line of oil that I would use from them for precisely the same reason. Only so much money and ingredients can be put in a bottle of oil and the more you spend the better stuff you get.
 
So what exactly did you mean then?
Ok. I've used M1 oils since 1978 and have never found an engine with any visible sludge or varnish at 10K OCI. M1 oils have an outstanding record here for keeping engines clean. The tri synthetic era was a long time ago, but I have found the M1 oils in the last 20-25 years have once again kept my engines very clean even with high mileage engines like my present Ford Fusion with 333K, again with 10K OCIs. The so called vanilla M1 is still and outstanding product with OCIs good for 10K and beyond. Now with direct injection turbo engines I might drop back to 7-8K perhaps, but I have no need for turbos. I have talked to Mobil tech and they have tested turbo engines and they claim that M1 10k oil will actually surpass 10K by several K. So I just roll my eyes when threads present other oils clean up dirty engines that used M1 oils, especially with 5K OCIs which for most engines is a waste of oil and filters. This is my 07 Fusion at about 330K. Any discoloration is residual oil. and not varnish. Nothing was cleaned up.

Just because you have seen those kind of results doesn’t mean everyone will. You have been running “vanilla” M1 in engines that are very easy on the oil, and I doubt you are pushing them that hard either.

I still stand behind my belief that vanilla M1 is not going to give a lot of people as clean of an engine as they would get with M1 EP or ESP or Truck & SUV. Those are much better at keeping a higher stressed engine at its best.

We do have people on here who used vanilla M1 and still ended up with an oil burner, that was later solved with VRP.
 
The OPs 2024 truck might well still be under warranty. Is 5W-30 M1 EP Dexos? I don’t think so. I understand it’s a million to one issue, but I always hesitated to put it my new Chevy.

Edit: I’m lame….looks like it is.😔

Generally oil burning is caused by coked rings and M1 oils will not coke rings at reasonable OCIs. I'm sure Valvoline makes fine products, but some here has turned their products into Snakeoil pandered by well meaning enthusiast. I've always said that if M1 goes out of business Valvoline is y next choice.
 
As always it’s engine and condition dependent.

Heck we use to go 300k on conventional and syn blend. Blanket statements on any brand don’t fly anymore, even M1.
