LPG Discussion Forum

hi all.

I'm about to run out of valve-saver flashlube liquid for my Forester and was wondering, seen as its very expensive (£19 for a litre) when doing the amount of miles I do, if you use anything else instead?

It's a lubricant so......

ManyThanksInAdvance..

Flash lube is availabe at about £13 per/ltr inc vat if you you dont mind buying 5ltr, if you are doing a lot of miles it could be the cheapest way forward.

If you decide to use other brands due to price, just bare in mind that the oil itself may be cheaper but having valve seats replaced is not!
That said I use JLM as well as Flashlube, dont think there is much between them in quality, probably not much differance in price either, but you never know you might get lucky!

I use this stuff -

the Polish guys that did my conversion say its as good if not better than flash lube, they should know, they've been driving on gas in Poland for a lot longer than we have over here..

Yes but have you seen the state of some of the cars over there? Not to mention the state of some of the conversions.......

agreed but the op's point is about lube, not the state of conversions, cars etc... All I was saying is they have been running cars on gas for longer than us, so should know a thing or two

hi JLM oil just for £9 vat inc. for 1L. in 5L tank
http://www.lpgshop.co.uk/jlm-valve-saver-fluid-5l/

hmmmmm, when I click on that link it says its £44.78 for 5 litres !!!

I think....
He means per litre, if you buy 5 litres.

so its even cheaper:)

£8.95. But how much Is the carriage ?

Don't forget that if you have a Flashlube system it will be calibrated for Flashlube oil. If an alternative is a different viscosity, which it almost certainly will be, you'll either negate any savings by using more of it or not be using enough and still end up with VSR.

My reference to the state of vehicles in Poland was to indicate that a little VSR would be the least of most owners worries.

..that's great Bobby, but the site isn't working for me. I can't remove the and to get at the lube underneath and therefore can't order..

I'll keep on trying.. Nice price.

click on the link then press "reload" or "refresh" the arrow thingy that goes round (on your tool bar it gets rid of the pop up offer

£51 odd for 5 litre's including carriage, not bad cheapest about doing some searching for a refil

last 5 litre's lasted me 12 top ups on my romana system (Aug 11 to Apr 13) so decent value based on months per tub

Lets face it any top end combustion chamber lubrication would be better than nothing when useing LPG. I'm a Yorkshire man so anything that's a bargain is obviously a good thing. My thought on this subject was how's about the efficiency of useing a modern synthetic two stroke oil,these have low ash properties which won't effect catalists, lube upper cylinder and the slight soot (afterall this is wot cussions the valve upon its seat) would surely be of help to supress valve seat issues. Any body have any thoughts on this? I have tryed to find info into wot is in flashlube and so far found buggerall, must be top secret. Over the last few years I have read a number of posts on forums reguarding top end lubrication, fuel pump lubrication etc on diesel,petrol and now on lpg and so far babyoil has been the most unusual fuel addative.

how does the flashlube system work

is the a pump that supplies it and the higher the revs of the car the more flashlube?

or is it some form of a dripper that you adjust the nozzle to let it flow on

Yes.

That is to say, there is more than one kind of delivery system.
The older/cheaper/simpler drip feed relies on manifold vacuum to suck fluid through a metering needle valve. Drawback, more load less fluid. But it works out on average. Except for supercharged/turbos, where its pretty useless. Only kind suitable for carbs.

The more sophisticated/expensive electronic system monitors fuel injector drive pulses and injects fluid according to fuel consumption. Accurate and works with turbos. No good for carbs. If you monitor LPG injectors it will also only work when LPG in use.

A sub-division of this kind injects the fluid at multiple points instead of just at the throttle, gauranteeing an even distribution across cyls instead of hoping for the best.

obviously the drip system isnt the most accurate way of doing it but anythings better than nothing. supprises me the lpg fitters dont try to push the systems as it obviously is of benefit to long service of the engine.

Sniff GreenAdd blindfolded and you'd think it was diesel... I wonder if someone is getting rich adding colouring to diesel

I use different lube systems on different vehicles - The ESGI lube kit is cheap, has a massive reservoir and comes with a litre of fluid (others come with less fluid). But it's too big to fit in a V6 Jag engine bay. Greenadd system fits in a V6 Jag engine bay but I'm fitting a Flashlube on the one I'm converting at the moment. The Suzuki next week will likely have an ESGI lube. The supercharged RangeRover the week after next will have an electronic Flashlube.

I've wondered about the effectiveness of different lubricants. Flashlube has the brand name, JLM reckon they've done as much research and their product is just as good. What do we all think? It's hard to compare lubes because the time frames are too long and there are many variables (driving style etc) to consider.

Depending where you buy Flashlube kits there's about a 100% difference in price! I don't stock much fluid - I used to sell it at cost price but I now point customers to the internet for refills.

They all seem to work. I have used all makes of lube with a drip system on my Outlander after bad valve seat rescession in 30k miles after conversion without. After 65k more miles the engine still ticks over fine instead of the hunting I had without valve lube.
Would not like to be a test case for using any other type of oil but I bet one would work though.
