Recall = M1 0w-40

[the blur]

GM just went with 0w-40 in their motors that are spinning bearings. Makes you go hmmmmmm.
Newish Escalades, and other newish motors that are blowing up. Big recall.

Makes me sadly LMAO if GM thinks that is gonna keep the L87 from blowing up.

Might delay it from giving up til after the powertrain warranty lapses; that's as far as GM gives a damn.

Remember when it was perfectly reasonable to assume that, if a GM V8 didn't make it to 250,000 miles, it was safe to blame the owner / operator?

Last year I had a long discussion with a buddy that works in the local GM service department, when I was going through my wife's Escalade L94, AFM delete, etc. Per his advice, I've been running a 5W-40 full synthetic that's labeled for European cars. I now see he was on the right track...

On our 03 Hummer with the 6.0 iron block, all I run now is the 5W30 Valvoline R&P.

I think a zero weight for cold starts is way too thin unless you live in Prudhoe Bay Alaska in the winter.

I remember it being time for a party and a parade if you could get to 100,000 miles.

Since the 80s, any NYC cab's engine that did not make it to 200,000 miles was a black mark on that fleet mechanic.
Then again, oil changes every 2500-3000 miles were the norm back then.

I have to agree.


Inspection and Repair Process
Dealers will:

Scan for DTC P0016 (related to crankshaft/camshaft misalignment).

If the code is not present, the vehicle passes, and GM will:

Replace engine oil with 0W-40 full synthetic

Install a new oil fill cap and filter



something else is going on. how is a crank/cam misalignment because of oil?


possibly vvt issue because using engine oil as hydraulic fluid to Active things always feels iffy to me?

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.

 

[rdezs]

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