Friend of mine gave me Castrol 0w40 jug that he does not need anymore for his new car.

But my 18 Camaro SS require Dexos 1 5w30 or 0w40/5w40 Dexos 2 (or Valvoline MST) for track uses. Other two house vehicles takes 5w20.

Should i use it for Camaro? Castrol 0w40 isnt Dexos 2 but i know its good oil like Mobil 1 0w40. Now its 100 degress outside during afternoon.


Thanks

I'll guess the high-calcium formula in Castrol 0w40 won't cause LSPI in that particular no-turbo, but DI, engine. I think LSPI has mostly afflicted the small 4's in GM's universe.
Therefore, use it. Don't advertise the fact that you used Mobil 1 0w40 to GM if you have a warranty claim though. Maybe it won't be an issue with them in the event of a spun bearing or some other kinda rare warranty damage.

As of about 2 years ago, and maybe it hasn't changed, Castrol 0w40 has about 1700 ppm Ca. Thats actually not too bad. Should be basically LSPI resistant. IF that engine every really did it.

someone this past week posted a current UOA on Castrol 0w-40 that showed high Calcium again....around 2500 ppm. So hard to say what they have at the moment...unless 2-3 yr old mix was being used.

0w-40 is probably the grade the Camaro should be using if CAFE didn't play a role.....especially if the car is driven hard at times in hot weather.

OP won't have to worry about disclosing his Mobil 1 0W40 use because his friend gave him a bottle of Castrol EDGE 0W40.

High calcium causes LSPI in DI engine?

I honestly do not sure how using a non dexos oil can causing an engine issue. Id thought Dexos for fuel saving / longer OCI and emissions ( such high zinc/pho can damage catalyst convert)? No?

Yes, "high" calcium, maybe defined as over 1500 ppm or so, has been blamed by the oil makers and engine makers as causing LSPI. Also, sodium is bad too.
DI engines with no turbo can suffer from LSPI. Most events have been with DI+turbo engines though.
