Lpg tune up

I'm paying 59.9 in bp filling station in southgate in North London, so every 24k is about 18monthly 2 year intervals then?

depending on what sort of mood im in l get about 215 200 on 75 ltrs gas and not much less towing the wobble box so lm realy happy, the down side is when the wife gets her hands on it its any bodies guess what milage straight into sports mode and its like we are at brands hatch on a game on the ps4

My classic gives 14 to 21 depending how I run and if towing.
If you want better LPG consider the ignition timing may be set for best of both fuels and setting for LPG will improve mpg and power quite a bit.
For servicing there is very little to do, change filter? Check fuel mix but if that were out not man may spot it.
Its more important to get the inginion system serviced a little more often as LPG is more sensitive than petrol.

Morrisons is now currently 62p/ltr (52p/ltr if you do your shopping there with 10p/ltr off fuel vouchers). Happy days

No, not yet. Been hectic with work so not had time to look myself. Booked in with my indie on the 5th Jan so see what he finds.

With the 4.6 being efi how do you set the timing for gas? Is it a computer jobby? Will definitely take it for a service/tune up in the new year and see about getting it tuned to run better on gas, all the plugs and leads are brand new on it. Just filled up and I got 200 miles from 78 litres. 120 miles was motorway between 70-90mph and the last 80 were through heavy Central London traffic (hammersmith, wembley, Wimbledon) so didn't think it was too bad, cost £48 to fill but will definitely look into getting it tuned to see if the mileage can be improved upon

EFI = fuel

You need to consider ignition timing.

l had a problem with mine basicaly the so called specialist hadnt a clue. l narrowed it down to a petrol fault purchased a blue tooth obd adaptor read all the faults to see if the gas had triggered the faults reset and hey presto it goes like a missile on petrol where as before you couldnt get out of the drive on petrol had to warm it up get it on gas then u could move. since i reset the codes we have done 3000 miles uk and continent and no probs. going to check see if any codes come up but im over the moon now.

Never had any problems with petrol or gas power wise it goes like a bullet on both, I'm just wanting to make sure the gas mixture is set ok and in not just throwing gas down the exhaust for no reason. I wouldn't mind a fault code reader but don't know which one to purchase because £500 is a bit out if my price league for one of the good ones

What your reader has done is reset any fault codes and also reset the fuel trims.

I have a generic reader that when you hit clear codes, it also warns you that doing so will reset the fuel trims as well.

I can only guess yours has done the same, and the fuel trims were well out of whack running on gas for so long!

A Nanocom comes in at a good bit less than £500 especially with the exchange rate at the moment. Blackbox Solutions Ltd - Designers and manufacturers of the best vehicle diagnostic tools.

yes saint v8 the guy who fitted at chorley hadnt a clue it ran like ****e for weeks even took it to france and back like that he said it was the cam.our fitter at work has a good code reader he reset the fuel trims first time the performance was out of this world even now its good but just dropped off a bitits going for mot this week so we will see what comes of that but i think it will b 2 new lamba probes for new year but yep the fuel trims must have way out

well iy walked through its mot emissions right on the limits so going to have a look proper i think the lambas are first port of call

I rang my local brc fitting garage and asked for a price for a leak check and service as it came in at £65 going to go see him in a week or so once I'm back at work. Seems a fairly reasonable price to me. I had the old girl mot'd last month sailed straight through but couldn't remember if she was set to lpg or petrol
