Thread: E85 Conversion, anyone done it?

I had my 2008 CRV converted to E85 about 2 months ago after considering LPG which we ran in our Mazda 3 before selling it. For just under 7k I thought I'd give it a whirl.


The installation took about an our and the garage informed me to change the fuel filter after the second refill which I did. He also mentioned I'd notice a slight performance increase but the savings in fuel would be obvious.

Anyway, I can confirm the savings are good. To fill the tank previously if I ran it nearly dry took just under 2k to fill. Average refill was about 1700bht if I filled just when the light appeared. After the conversion my cost is 1100bht or there about.

I can't say I've noticed any performance gains, having said that the fuel type does make a difference. If I use PTT E85 my average urban mileage can drop to 7.5km per ltr, but with Green Leaf it increased to 9.5. There is a huge performance difference between the 2 fuel type also. Green leaf is much more responsive.

So far I'm chuffed with the savings.

^half price, very good.

LPG worked out at half price too.

NGV worked out (if I remember correctly) at 1/4 price, but the upfront costs were higher and suspension mods needed due to the tank weight. Thus, only worthwhile if you bought a car already altered by the manufacturer, imho.

What do you reckon on the E85, JJ?

Cost of Installation vs time driven I'd say E85 is more cost effective.

Example: I use my car 3/4 times a week from BKK to Min buri.

If your car is going to be sat most of the week, the expense of LPG isn't worth it.

From a full tank of 95 and E85 it is near impossible to tell. On a good run I get just over 600k on a full tank. Similar to 95. I've seen some reports saying they get less mileage per tank on E85, but I haven't experienced that. The big saving in fuel cost outweighs the slight difference in mileage, if any.
