Cold Morning Engine Pinking

[Billy1972]

Hi, I have just purchased a 2017 3.2 Wildtrak Auto with 15k miles on the clock.

I've noticed first thing in the morning or when the truck is 100% cold my truck has an engine pinking sounds when I accelerate, however once half a mile down the road and its slightly warm the pinking sound stops and she sounds fine for the rest of the day?

Is this a case of cheap oil from the previous service or something all 3.2's do?

Thanks

I’ve had mine since Feb and its just the same. Sounds like a bag of spanner’s!
