Recall = M1 0w-40

Not sure how any oil would affect port injection. Pretty much out of contact with the oil.

pvc systems are all horrible these days. everything drinks as much oil as gas, that's why every 50k you gotta walnut blast the intake ports and valves. plus what gets by the rings. the non direct injection oil makes tons of ash in a direct injection engine. they need a lot of specific additives to stop that but the trade off is they don't have as much of the anti wear as a good port oil has.


so of course it works, but it's better to use one in the correct application.

I seem to remember the euro spec oil has a lot of stuff in it for direct injection euro emissions that isn't the best for regular port injection. might be a better quality 5w40 to use? I believe gm has one they call super car oil for their lt5 engine.

I have run M1 Euro 0w-40 in all 3 of my LS engines. I'm currently running it in both of my Gen4 LS engines.
Good oil.

I run the 5w40 in the hot months only. 5w30 the other 6-8 months.
IDK if it's the best. But I certainly like the idea of a little thicker
oil in heat (and while towing). Still get the benefits of the cold start 5W
Of course all is full synthetic (use castrol or valvoline only)

so this is the one I was thinking about, not only was I backwards. it's OK for normal. engines, it's bad for di. also this is a old video about an old oil blend. they seem to have since updated the formula.


I don't take his word at 100% but it is an interesting take.

as for running it, honestly you could use the lowest quality conventional oil on the shelf and be OK if it's not races or heavy tow. at this point I'd be interested if you could find a oil that was bad enough to show. high wear in a oil sample of a normally good running ls.

A lot of GM vehicles in Australia are marketed under the Holden brand. Granted, it's a little bit of a warmer climate, but 10w40 synthetic is readily available there. (And recommended by the Holden literature) Of course, they're not subject to the CAFE standards we have here in North America. I think GM just learned a hard lesson running 0w-20 in the brand new vehicles of the 6.2 that are all now recalled.... And now even GM is recommending the 40 weight in those.

It's worth noting that my wife's 2014 Escalade, they recommend 5W30. You had a co-workers 2014 Sierra pickup with the same engine, 0w 20 is recommended. It's in his owner's manual and printed on the oil cap. Different recommendations for the same engine, the only difference is the fuel economy standard they're trying to meet for two different models. When politics start dictating lubrication versus fuel economy, it's definitely not good.

so I might have this wrong because my eyes go crossed after reading about oil for longer than 15mins. but I believe the base oil thickness is more based on the first number and then the additives are added to get it up to that 2nd number.

so say you didn't need that 0w for cold starts for your location in summer running a 10w40 oil in theory starts. with a thicker base oil and would need less adjectives to get to 40. so you end up with more room in the package other important stuff and would take longer to sheer down to a lower grade. like they sell a 0w50 but if you were to do a track day, 15w50 would be a better choice.

again, mean nothing in real life. but at least that's the way I thought I understood it.

in your case yeah, but I will say some cars have started using the same cylinder technique as motorcycles have for a while, where there's some type of coating and it makes the hone process completely different. the one I've read about was the Ford gt40, I believe the newer v6 one. it's calls for thin oil, but as performance shops started to turning up the boost they ran the normal racing oils. it gave them trouble because the hone type, liner plating and ring package couldn't keep the thick oil out of the cylinders. burning oil in a big boosted engine kills come of the detonation resistance of the fuel.

I believe some of the newer Honda engines that call for 0w8 oil use the same tech. putting a 5w40 on there might not be about fuel mileage. it might also be OK, but I wouldn't want to he the first to try it.


I have personally seen the opposite as well, we have v10 ford's in equipment at work that is normally diesel powered, constant high load for hours on end. they call for 0w20 but using it they will burn their 4 plus quarts and shut down long before scheduled maintenance. engineering said they need to break in lol, they never did. we
put 15w40 delo conventional diesel oil in tkem and they almost make it the 500 hours between pm now. much easier to keep up with oil checks.

will it damage the engine? so far I see no signs, plugs look good. the Ford v10 is not known to be reliable anyways.

2014 escalade is the L series engines... 6.2 Gen 4 FOUR
2014 Pick ups are the newer gen 5 engines with Direct Injection.
So those are 2 very diff engines (same year).. GM held over
the SUV's in 2014 while the pickups were the all new design

Ah, that makes sense.

I'll take a look under his hood tomorrow and see if he's got a fuel rail.... Probably depends how early or late in 2014 it was manufactured?

When it was manufactured means nothing it's the year of the truck that makes the difference.
