LPG Vs Super unleaded

[SAVA9E]

Ive heard a lot about that its important to run the Legnum on super unleaded, but what about LPG, is it safe to run on it?

[Confused]

LPG is a completely different beast to Super Unleaded.

It require a special system to be installed. There's a thread (http://www.clubvr4.com/forum/showthread.php?t=46229) on the subject just below this one, which would be worth a read.


However - for petrol, you MUST run the VR-4 on Super Unleaded, as it is closest to the 100 octane fuel over in Japan.

Racing fuels, Avgas and LPG typically have octane ratings of 110 or significantly higher.

Because the computer would be setup to provide the correct mixture and timing for LPG. Our computer is setup to inject the correct amount of fuel and ignition timing for 100.

Most systems switch between petrol and LPG depending on load. So you would need to continue to fill up with vpower/super unleaded. VR4's can and have/are being run on LPG, so long as you get system that can supply enough gas you'll be cool, you will save some cash in the long run but you would need to keep the car for a couple of years depending on milage.
