300,000 kms on VO

Post by caveman »

Just wanted to mention that between my old 98 TDI [now owned by a good friend] ,my 1990 Transporter , and another 98 TDI i bought from an old customer , have now racked up around 300,000 kms on VO, all with 2 tank systems i installed . Absolutely zero issues from running on VO. The 98 i just picked up has 420,000 plus kms and the compression on all 4 is 400 psi. So much for wearing out cylinders from VO washing past the rings.

congratulations. My '03 Jetta TDI has about 12,000 miles since I started burning grease in it and so far so good.

Most vehicles do fine on vegetable oil if the oil is clean and hot. But someone will always be around to tell you that it can't be done. I wish you many more greasy kilos!

3 key items for veg oil running

1 clean oil (and no water)
2 hot oil ( over 160 F )
3 start AND stop on diesel (easy cold starts and no coking the injectors)
1992 Jetta (gasser to TD 1.6)
2000 TDI Jetta
1990 Jetta (Gasser RIP @ 875,000Km)
1976 Rabbit (RIP)
1972 Superbeetle (RIP)
1971 Fastback (type 3 RIP)

Just an update. Opened up the pump today on the 98 AHU that i bought from an old customer i had done the conversion on which has done just over 100,000kms on VO. Pump shows no internal wear at all, and other than a small brown discoloration which wiped clean, looked like it always ran on clean diesel. No gunk which i've seen on conversions that were done improperly or with poor WVO. Engine compression with more than 430,000 kms total was 440,440,440,410
