Beating the Gas Prices... HOW?!

[270_BMW]

Evening Everyone,

There is a question that has been burning in the back of my mind and it's one that I really would like to know what your thoughts are.

I own a 2006 E53 with the 3.0L Straight 6, and just over 100,000 miles on it, which I am the second owner; I have taken care of this car at every turn since it came to be in my possession. A little while ago I came across a 2005 Land Rover LR3 (Discovery 3) which has the BMW 4.4L V8 that had 180,000 miles. I parked the E53 to drive the LR3 as a daily and to do some much needed work on the E53. All the work is finished on it now, but with how gas prices have been... I've just been letting it sit.

I will admit I put some mid-grade 89 in the LR3 with some purple power octane boost or STP octane boost... but it was clear that the engine didn't like that and it sounded like the engine had bronchitis with no power at all. I ran some seafoam through it and ran a tank of 93 premium through the LR3 and it's getting back to where it was before.

Right now I am driving a 2017 Taurus Police Interceptor which takes bottom of the barrel E85 which around where I am right now I can get for 2.30/Gallon.. or 1.30/Gallon from Meijer... which is great... but Premium is still 3.99-4.44/Gallon... So on an E53 or LR3 top off, we're looking at least double the cost over 100$ in fuel every two weeks.

E53 has only ever had premium... shaking the cobwebs off it this evening before Winter sets in reminded me how nice it rides by comparison to my Interceptor, but I don't want to harm the engine and can't really afford the 1.50-1.90/Gallon up-charge right now.

How do you keep your BMW happy with these crazy gas prices? Or are a lot of them sitting right now?
