Premium Petrol? ..or Regular? ...or Mid-Grade?

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.

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
