LPG

[Digger41]

Anyone here running their W126 on LPG. I looked at a 380SE that was running on LPG last week but the owner decided not to sell it. ???
I then found a very good looking 420SEL with 459,000 km's on the dial. (my wife had a fit when she found out the mileage, but it is so sweet to drive except for the rear suspension.
So any experience of LPG out there. It costs about 66C/lt here in Perth at the moment, as against A$1.49/lt for petrol and the gov. pays A$3000 towards the installation costs. I got a quote of A$3200 to install but guy says he has not done one before. If anyone has a 380/420 converted can they please let me know what the mixer is called, numbers etc.
Thanks in advance,
BrianD.

You are going to get Teutoned(tm) or Cascaded(tm) very soon if you don't search the forum, since we have already covered that topic here.

Here in Peru many cars run on LPG and CNG. Basically any gasoline car can be converted to LPG, the conversion is really brand-independent. Progas (Progas - Professional Performance -- argentina) sells a mixer specially made for the V8 motors (it lists as Mercedes V8 500 SEC mixer), and i bet many more companies have a mixer that fits perfectly. By the way, on these cars the mixer is usually installed on top of the air flow sensor plate, so you don't remove the K-jetronic system and thus the car remains dual-fueled (LPG or gasoline/petrol).

Or he gets Jeroened!
Not too many cars on LPG on this forum so there's not much info in the archives.
Please (re)read the "welcome to the forum" sticky on the first page.
It'll show you how to fill out your profile and do a forumsearch.

I have LPG in my 500SE. No problems so far, the setup is a Lovtec(Lovato)+BRC combination. The cost of installation was 27 000 CZK ($1600). The car draws 13-18 l/100km (about 2 liters more than gasoline) - it's not a direct injection (btw don't try it, too expensive and AFAIK will not work in M116/M117!).
Also, the car idles much smoother and has a lot more torque in low/mid RPMs. It only lacks power above 5000 RPM (but still beats gasoline power ).

Yes, member Andrew SL&SEL has put his 420 SEL on to LPG and is very happy running on LPG - it doesn't matter which mod it is - if ou haven't used the search function, you will be told to...

Pretty close on the username Ross [thats my ozbenz username] but to make it easy for Brian, here is the thread link.

It seems LPG is mainly an Aussie or Euro mod as our American friends still have cheap petrol and really don't seem to need that LPG fuel saving. The other big tip for fitting LPG is to always start and warm up the car on petrol. Switch it to LPG for driving but switch it back to petrol when you park. It stops the fuel distributor from drying out and helps ease the burden on the valve seats. I generally run the car on petrol for short trips and use the LPG for the long drives. Touch wood, it's running like a dream

Please fill in your signature so we can get a bit more info about you and your car Brian.

Just an FYI.

I think I remember someone recently asking about stiffer springs for the rear of his 420 SEL.

The owner had installed LPG equipment and tank in the trunk and now the car's rear end was sagging under the added weight.

You may want to consider a car that has the hydraulic Self-Leveling-System (SLS) rear suspension.

You might need a bigger converter or a thicker gasline from back to front.

I have regular (new) springs and regular (new) shock absorbers in the read, gas bomb in the trunk in place of the spare wheel, and I usualy travel with trunk full of junk - it's not sagging down...
