We have a 10 years old Isuzu (Thai-Rung) Wanderer Station waggon which is running just fine even with about 190,000km on the odometer.

Now most gas stations in our area have stopped selling regular Diesel and replaced it with 'Bio-diesel'.

What would be the long term effects on the engine if we fill up regularly or only occasionally with Bio-diesel?

How is the mileage(Km)/Ltr. for bio-diesel compared to regular Diesel?

Right now my wife gets about 600-650Km out of a 40 Ltr. tank (I get about 500-550Km out of the same tank - must have something to do with my driving style and speed) of regular Diesel.

You should be able to run bio in any diesel engine. There should be no difference in performance, mileage etc. The stuff they sell here seems mainly to be B5 or 5% bio-diesel to 95% petro-diesel. Even B100 (100%) bio-diesel is fine. There are not the same issues as ethanol enhanced petrol. Well refined, 100% bio-diesel is considered by many to actually be superior to petro-diesel. Some cars will even run on vegetable oil without converting it to bio-diesel without any problems. Remember, Mr Diesel originally invented the diesel engine to run on vegetable oil (at first peanut oil)!
