Premium vs. Regular unleaded - Land Rovers Only

bonemonkey · 10-01-2004, 09:17 PM

The newer Disco's call for premium unleaded gasoline. Does anyone know if these have a knock sensor? If so, could we use regular gasoline? Anyone currently running sub-90 octane with no probs?

We have a 2000 and it runs fine on 87 as we speak. We put in a tank of 92 ever so often.

I have a '95 Disco (which also calls for premium), and it sounded like it was going to die with 87 in it, when I put in 92 it sounded much much healthier.

My 99 runs fine on 87.

They will run on 87 but you will loose gas mileage and power.
It is OK to run 87 if you have to and it will carbon up your engine big time if you continue to use it.
In the long run it will cost you more to run 87.

I don't own stock but I try to only put Chevron in mine. I've had a couple of really good mechanics as friends and thats what they put in all thier cars. The additive helps keep things clean. I've used the Unleaded (midrange) and get fine results but switch on occasion to the high grade. I burn a lot of interstate miles I don't know how that plan will work with constant stop and go traffic.

i have heard the same thing about chevron.

Toddicus · 10-15-2004, 07:31 PM

well no wonder i get crappy gas milage with 87 =c)
i'll try using better...but i've never had any knocking issues or anything of the sort using 87.

over the long run what you save from running sub 90's will cost more in a valve/ head job. these land rovers are known for sticky valves so why compound the problem but adding to it?
take care

Dent,
I couldn't have said it any better. As the old saying goes," Pay me now or pay me later", only problem is that you will pay alot more later then what you, THINK, you are saving now. If you are the type that likes to get out off road you will also loose in perfromance.
