Was trying to find the right place to post this. But I have a 6.0 2001 Yukon denali with 200k miles. I’ve had it for 3 years and the previous owner told me he always used plus grade gas. I’ve always used but now that gas is crazy high and plus usually .25 more per gallon am I able to switch to regular unleaded? Or will it damage the engine or limit performance?
