Re: [MBZ] extended oil
But you are special, Roger. The rest of us have to live with cold garages that tend to induce moisture build up as well as other troubles associated with not getting engine upto temp regularly to cook out the water. clay 1974 450sl - Frosch - Two tone green 1972 220D - Gump - She is green, simple and ran 1995 E300D - Cleo - Used by the Queen of Denial POS 1987 SDL - Beware Nigerian Scammers On Oct 26, 2012, at 8:52 PM, relng...@aol.com wrote: ...I can see that being an issue.

Hi Ernest, In the overall sense of things, the number of people using BioD is still pretty small.

[MBZ] extended oil drain intervals for synthetics used with BioDiesel (was: Re: Here come the diesels!)
hi Larry! seen anyone do any comprehensive oil scanning on diesels using synthetic oils with B100? i haven't been able to get anything from any of the synthetic manufacturers about what happens to their products when using BioD; seems that on one hand, the need to change oil so often in our 617 would be reduced on the basis of soot buildup (because there basically *isn't* any), but on the other hand i'm wary about extending drain/fill intervals because of the increased solvency of BioD and uncertainty of what it does to the synthetics. for the last 50K miles i've been using B100, i've been doing 3K changes while using Delo, because it's pretty obvious that the BioD breaks down the oil faster than #2. cheers! e LarryT wrote: We've done a number of TBN (total base number) tests for customers over the years and they all seem to say the same thing - the additives that control the acids created by the combustion process are typically exhausted by around 7500 miles.
