It all makes sense. A lot of good experience and knowledge from the users on this forum. Thanks All!

I recently purchased a 21 Reserve L. Reading the manual it states "Your vehicle is designed to operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87" but then two paragraphs later it states "For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer". What I take from this is you are Okay to run regular fuel as long as it is at least 87 octane, however, you will get the best overall performance running premium fuel with an octane of 91 or greater.

Yes, this is mine! I just purchased a new 2021 Reserve L and took delivery last week. I traded in my 2019 Cadillac Escalade ESV. No regrets. They are both nice vehicles but I like the Lincon better.
