Hello, I purchased a left over 2018 Yukon from my local dealer. When I accelerate I hear what I call a ping noise or rattle coming from the engine. Reminds me of the old days when I was young and needed a higher octane fuel for a muscle car. I brought it to the dealer and they said they could not make the noise, they didn't try very hard. Just thought I would reach out and see if anybody else is experiencing this issue.
Sounds like poor quality, low octane fuel is being used. Top Tier 93 baby, actually costs less to burn, especially over time.
