Thread: Declining fuel economy from 300tdi

I'll also replace the fuel filter and after I do that I'll sell a kidney and try some BP super diesel.

Will report back in a month or two.

Thanks for all the great ideas everyone.

Quite a few people recommend rechecking them every 10,000km

An interesting thing I found with injector cleaner, I ran a can of Liqui Moly Diesel Cleaner through the Landy and it did make a difference. For one tank then it must have just gummed up again. Tassie diesel is horrible quality

been looking at the provents too.. but as i have 2 td5s...

I'd be checking this just to be sure also...

As for BP ultimate... i lost a 100k's on the disco td5 the one time i tried it.. we generally use peak in both.. as we get the discount and the servo we use is the cheapest around (even over other peak servos)
