I have to admit I never heard of lpg in cars before joining the forum. Never seen it at a fuel station in South Africa either.
Fuel is cheap in S.A. compared to europe so no real need for LPG. I used to live in Springs many years ago.I have to admit I never heard of lpg in cars before joining the forum. Never seen it at a fuel station in South Africa either.
The vid made it look as though they poured the stuff in the tank, put the car straight back on the rolling road and saw immediate results... but the stuff would need to go through the injectors (meaning best part of a tank of fuel would need to be used between rolling road tests) for the stuff to be able to go through injectors and have any effect on injectors anyway. By the time a tank of fuel had been used other variables (including weather) could make more of a difference to bhp than the cleaner did. Petrol injector cleaning potions can work (and the trade has better ones than Redex) but I reckon they intentionally picked a car which they knew had slightly gummed injectors ('when I previously tested this car I noticed it had hesitation between 3000/4000 rpm, but the hesitation seems to have gone now') and knew injector cleaner would have a good chance of working on that specific car. When injector cleaning potions don't work ultrasonic cleaning can, when that doesn't work you're looking at new injectors. The trade wouldn't add a bottle to a full tank, would wait until the tank was nearly empty, add to the tank and go for a blast to concentrate the potion going through injectors - Wouldn't expect the potion to have that much effect except for on a car where injectors were known to be gummed / spray pattern off, where cleaning potions have best chance of improving matters.I think the best thing to get the maximum mpg is to put something like Redex fuel cleaner into your tank it's proved to work. I only do town work and in the summer I roughly get 21 miles to the gallon in winter it goes down to 18 to the gallon and that's not taking it particularly easy. I haven't done any long runs yet so I can't comment on that.
Watch the video give you some insight.
If you have never used it put twice as much in a couple of tank fill don't expect it to work straightaway it will take time but it's definitely worth doing.

Averaging at £1.30 for petrol.How much is petrol there? Next month it will be more than R17 per litre here.
Oh gosh ouch.Averaging at £1.30 for petrol.
Most Elgrands that suffered cat problems on this forum only ever ran on petrol (were not even LPG converted).I have been told locally by quite a big garage that when a vehicle is converted to LPG it causes more heat in the engine which was originally designed to run on petrol and This extra heating contributes to the catalytic breakdown. Is this potentially correct? (Im only asking!!)
Thanks for that @Lpgc ;-)Most Elgrands that suffered cat problems on this forum only ever ran on petrol (were not even LPG converted).
Cats have to be above a certain temperature to even work, when they are working (doing their job as normal) the catalytic action creates more heat (so the cats effectively get hotter than the exhaust gas that feeds them anyway). One of the biggest factors effecting how hot the cats get is contents of the exhaust gas feeding them, regardless of what fuel the engine is running on the cats get hotter the richer the engine mixture and the more exhaust gas that goes through them.
If cats get too hot they will fail - But overheated cats doesn't seem to be the usual cause of Elgrand cat problems.
Thanks for the informationExpect poor economy. Really. I'm not gonna lie to you.
They are a 2 tonne bus with pretty appalling aerodynamics and large engines. They are designed for comfort and luxury, not for cheap motoring.
As a brief run down:
E50 QD32 3.2 Diesel - 26mpg average. 18mpg around the doors. 36mpg on long runs at 55.
E50 ZD30 3.0 Diesel - 28mpg average. 20mpg around the doors. 40mpg on long runs at 55.
E50 VG33 3.3 V6 - 18mpg average. 14mpg around the doors. 28mpg on long runs at 55.
E50 VQ35 3.5 V6 - 16mpg average. 12mpg around the doors. 28mpg on long runs at 55.
E51 VQ25 2.5 V6 - 22mpg average. 18mpg around the doors. 32mpg on long runs at 55.
E51 VQ35 3.5 V6 - 20mpg average. 16mpg around the doors. 30mpg on long runs at 55.
These are worst case scenarios. If you are getting less than this, you have a problem (either with your engine or your right foot). If you go into buying an Elgrand with these figures in mind, then you won't be swearing 6 months down the line when you are on first name terms with every petrol station attendant within 30 miles of your house.
R17 per litre is roughly equal to 90 pence and we are paying £1.40 for premium unleaded ouch !!!How much is petrol there? Next month it will be more than R17 per litre here.
I go for the higher octane on a refill . I get the same miles for the same amount of cash so why use lower octane unleaded ?Yeah but. We don't need to put premium in so its more like 1.30
Yes only %5 heat moreI have been told locally by quite a big garage that when a vehicle is converted to LPG it causes more heat in the engine which was originally designed to run on petrol and This extra heating contributes to the catalytic breakdown. Is this potentially correct? (Im only asking!!)
