I heat my oil just before the injector pump. It is good because the injector pump is not suddenly fed hot oil, and is "pre warmed" but is bad because diesel does not lubricate as well when hot. I use a blend of diesel/ veg oi as my start up fuel, which helps keep the lubricity up (and per barrel prices of crude down) I have a tap to turn of the heat if running on diesel for long stretches (which I avoid of course) and have an in line fuel pump, which is lubricated by engine oil, not fuel oil.
For some injector pumps (rotary for instance) it is not a good idea I believe.

Hi!

I am a newcomer at this forum and I will like to get more knowledge about SVO and WCO. I bought an old Mercedes, a 300D W124 and since I bought it I use SVO and WCO most of the time. I didn't do any improvement jet and recently I bought a pre heater device from the ebay (eBay: Eintanksystem VECAR Umrüstanlage 12 V PÖL Pflanzenöl (item 280104961608 end time Apr-18-07 03:15:00 PDT)) now I am thinking how to install it can anyone give me a hand on this matter?

Thanks
