Cold characteristics for those of us who live in cold weather is a critical parameter. Saying otherwise is silly. We'll be having single digit F highs and negative F lows this coming week. Having had diesel vehicles plug their fuel filters in extreme cold temps in the past, the cold flow properties are extremely important...
This is also something easy to test at home. You can take a sample and put it different containers with and without additive and test for yourself.
No supporting data that aftermarket additive do anything of value? This is just silly.
Of course, one can always find "reasons" not to believe measured data due to some aspect of the tradeoffs required in setting up the study, the cost of sample sizes, lab testing fees, resource constraints, etc.... |
When this presentation came out, the doomsday picture was frequent failed fuel pumps. That only happened, somewhat, with the CP4 Bosch pump. No other reports of failed pumps on a predictable scale.
Again, there is no reason to use aftermarket additives, only the belief that they might work. This is technically not "naysaying" but perhaps just a statistical argument.
