My son drives my 2007 ML CDI with the particulate filters.
The car has 260,000 miles
Between Mobil One oil changes sometimes you get a CEL message that says " oil a bit low top off at next fueling" or something like that.
So my son stops and buys Mobil One 5 w 30, but not the ESP formula, spec 229.xx.
He added a quart and drove about 100 miles with it.
Does anyone think that this mistake will jeopardize and clog the emissions system?
I ask because coincidently a new CEL came on today. I will have it read.
I had him change oil to the correct stuff today as he was close to the 10,000 miles anyway.
Any thoughts are appreciated.
thanks

I'd be surprised.

I would seriously doubt it.

I'd throw quart or two of the "proper" stuff in the spare tire well for next time and sleep easy.

yep sleep easy, a quart of m1 5 w30 will not do much to hurt it.

Should not be an issue at all.

Small amount and a short time, such "emergency" substitutes are expected.

Man if op was my dad i would be disowned. Ive done complete oil changes with 7-11 oil before...

I was tought that oil is oil and as long as ur changing it on time and keeping it full, then generally, you are good.
