What gas are you putting in your Landy Disco 1?
Premium?
Regular?
Mid-grade?
Jet fuel?
Paint thinner?!?

 

Unicorn tears and government cheese.

 

Premium for North American Spec trucks.

Always a good thing to keep back from Army about a mile..... woo doggy, gotta be the cheese.......

 

Premium. Helps keep it cleaner inside.

 

There were other vehicles in the late 80's and early 90's that experienced rampant engine failures ultimately attributed to fuel grade. The issue was excessive internal carbon build-up. Late 80's Cadillac engines are one prime example and if you read on Wikipedia, it explains the situation. I read the exact scientific reason for it one time and why premium fuel didn't cause that problem ....but it was a while ago and given my slow brain these days I can't re-recite it. But it's out there if you look for it. Our Land Rovers apparently fall into the same category. It used to be that Premium was only 25 cents or so more expensive than regular, but now it's WAY more expensive than regular up here. Still, I don't put a ton of miles on my L/R every year so Premium is a lot cheaper than engine problems to me, given the expense of an engine rebuild on one of these things.

 

I have run all 3 and see no real difference, the performance and MPG gain with super is minute IMO, I only run it on trips mostly

The lr3 gets it every tank

Someone just needs to find the magic formula to make these better on gas

 

This is my situation. Fuel is one of the least of my expenses. The last 4 years, I've been averaging a little over 4000 miles a year with a large portion of that off-road. Fuel prices have been very low, and I might not even spend $1000 a year on fuel.

If someone were commuting in one of these, I'd have to wonder why they're doing that, but it might make sense to run regular fuel in such a case. Their savings would go a significant way toward paying for a replacement engine, which they're likely to need sooner or later anyway, premium fuel or not.

 

I commute 80 miles a day in mine, in the colder months and why is a couple of reasons.

1. I like my Land Rovers
2. The discovery is warmer than the Defender in the winter
3. I like 4wd in the snow
4. The MGB sucks in the cold

I do run regular. I have put 30k + miles on the Discovery in 1 year of ownership

 

I run regular in my 96. My brother owned it before me for about 100,000 miles and always ran regular too.

 

I've been doing the Hi-Test & Mid Grade because it sat so long......at first I thought the truck had '2' tachometers until I realized the small on was the gas gauge.....
