Thx! That was my thought as well yet wasn’t sure of the 90 octane.I found this exact fuel combo when driving through GA in my LR3. That tank returned 20mpg driving 55mph on secondary highways with a heavily laden vehicle. 90 octane is still higher than midgrade and will be fine in the D1. If the price is comparable, use it. Even if not, use it.
Ethanol free gas has some advantages. If your truck is going to sit thru the winter I would put ethanol free fuel in it for the last couple tanks of the season. Ethanol turns to varnish really fast, I learned that the hard way keeping ATV’s and snowmobiles.Found a station that offers ethanol free gas yet rated only 90 octane.
What is the better way to go?
Also ‘96 D1.
The Saab and Rangie do not get used that frequently so both are good candidates for E0 gas. The Audi goes through a tank a week even in the Winter as ski car so E10 is fine. I’m thinking the D1 might run better with E0. At least I’m going to give it a shot now that it is readily available.I normally run ethanol free fuel in my Chevy Cruze. It’s an Eco model and gets about 42 mpg on ethanol free fuel and about 38 on 10% ethanol. But right now with gas prices the way they are I settle for the 10% stuff. Plus my car is going to die soon (I feel it) so I kinda stopped caring.
Also keep in mind that alchohol levels over 10% will cause o rings to swell and fuel pump seals as well.
