#9 of 14 So ... by hdominguez Nov 14, 2006 (9:45 pm)
Based on the feedback from the guy from Houston ... is it ok for me to use regular gas for an 05 LR3? I don't want to do it if this will cause long term problems or issues.   Hector Austin, TX.

Does it really matter? Normally premium gas is $0.20/gal more than regular. If you drive 20,000 miles/year at 25mpg, that's 800gal times 20 cents a gal more = $160/year, or about $3/week more in gas costs, or 0.01% of the cost of buying a $30K vehicle...we're not talking big bucks here! It's about the difference of getting 23mpg vs 25mpg using 20,000 miles/year at 25mpg = 800gal vs 23mpg = 870gal which is about an extra $160/year.    So you could look at the difference between using premium and regular gas the same as gettin 25 vs 23mpg, but for some, that difference is enough to buy another vehicle. I guess if everything else were equal between two vehicles except one costs $160 more per year to operate because it's less fuel efficient or requires premium gas, then I'd go for the one not costing the extra $160/year, but there are usually a lot of other differences between vehicles (in my opinion) more significant than this issue.

Replying to: bobw3 (Nov 17, 2006 6:30 am) Interesting analysis and point taken.   Unfortunately our Discos don't get 23-25 mpg but rather 12-14mpg. Being in California, the delta between regular and premium is more along the $0.35 / gal. So we're looking at $400-500 / year. My question was: can I pocket that without damaging the engine in my 2003 Discovery? (I know I'm ok doing that with my 96 Disco - have been driving on regular for 8 years without problems)   Thanks for all the replies - looks like nobody has had a real bad experience going that route.   MaxCattum Replies to this message: british_rover (Nov 17, 2006 11:52 am)

Replying to: maxcattum (Nov 17, 2006 11:35 am) I know plenty of people that put regular in their Discos and the only consequence seems to be a tiny drop in MPG.   Try it out for a few tanks and see how your mpg drops.   The knock sensor will retard timing if necessary so that should protect your engine.   If you are going to tow or use the Disco off-road you should put premium in it as you are straning the engine more.

Here is a very good explanation of octane ratings in fuel and how it has nothing to do with the energy content or quality.   http://tech.vtxoa.com/index.php?action=artikel&cat=3&id=22&artlang=en
