Sainsbury City Diesel MPG

(1/3) > >>

DogVanMan:
Has anyone experienced poor MPG with Sainsbury City Diesel..?

I run a Td5 110 with Porny's stage 2 mods (top bloke) and I'd swear I've been down on power and getting worse MPG over the last (full) tank of Sainsbury City Diesel. This is first time I've tried the stuff.

Over 275 miles of mainly motorway I've been down to 23.3mpg. I'd have expected at least 25mpg, probably better. (Porny's mods have actually made it slightly more economical at small and steady throttle openings, and although I've seen better than 30mpg on a steady run, this tankful wasn't an economy run!). After filling up at Sainsbury's, I noticed that it felt a little flat too. I Googled it and there are comments on other car forums to similar effect. Needless to say I've gone back to my usual stuff now.

Anyone noticed anything about Sains City Diesel in a Land Rover..?

Sainsbury's is the same as BP fuel, so what do you normally fill up with?

adafish:
I'VE TRIED THE bp ultimate today in the 300tdi...put £30 in at 101.8p a ltr, see how i do on that

DogVanMan:
I'm normally on Total or Shell standard diesel.

I think there are different additives in Sains City Diesel to reduce smoke, so it may well be different to standard BP diesel?

Another one to throw in.. Do I have it right that for petrol there are standards concerning RON valies (95, for example) but for diesel fuel there is no standard as to the minimum level of calorific value (If that's the right term to use here)?

The more RON, the better the performance.
However, I think the "Ultimate" in diesel relates to the emissions, not the performance.
