A question for SVO users - do you actually bother to titrate WVO to check the quality?
Titration for SVO http://journeytoforever.org/biodiesel_svo.html#titsvo Some people just chuck it in and go, others filter it and centrifuge it, which has no effect on the FFA content: >Acid contamination can and will damage your engine. Filtering has no >effect -- zero effect -- on the acid content of the oil. >Centrifuging it also has zero effect on the acid content. > >- The German PPO fuel standard (see above), the only existing >quality standard for SVO, sets a maximum acid value of 2.0 mg KOH/g. > >- Elsbett Technologie says oil that's too acidic can affect the lube oil. > >- The Fuel Injection Equipment Manufacturers (Delphi, Stanadyne, >Denso, Bosch) say it corrodes fuel injection equipment and leaves >sediments on parts. > >- Engine damage of a car using the BioCar SVO system was traced to a >supply of soy oil which was not the usual food-grade oil and had a >high acid content. "An examination of the defective sections found >substantial surface erosion of the hardened steel high pressure >parts, which are not acid-proof." - Straight vegetable oil as diesel fuel > Fuel quality http://journeytoforever.org/biodiesel_svo.html#gnl In Japan, with an Elsbett system in a Toyota TownAce, we only used oil titrating at less than 2 as SVO. If it was more than that we used it for biodiesel (which is much better fuel anyway, IMHO). Also, any comments from long-term users of two-tank systems - are they really inferior to Elsbett-type single-tank systems? Has anyone had difficulty getting a response from Elsbett? Thanks!
