At Walmart tonight b/c I needed to get some ethanol stabilizer (I use Lucas) for my 2 5gal cans I use to store E85 to use for blending in my Sportwagen. I struggle with winter fuel here in VA and getting a lot of timing correction which at times leads to power cuts as the ECU tries to protect the engine by dumping fuel to cool it down. I typically just add 2.5 gallons of "Flex Fuel" from Sheetz which has a range of ~50-80% ethanol....$2.56/gal...a bargain! I have a clean tank (no additional E) of Costco 93 in there currently and was having some issues getting power cuts etc. trying to hammer it WOT today b/c it's pulling too much timing. Decided to try this out, had read about it here:
So the math here is that this product mixed at a 100:1 ratio gives 30 points or 3 octane units according to that volvo article i.e. 93 bumped to 96. So, for the big $9 bottle at Wallyworld, that's 0.12 gallons (15 fl oz) to a 14.5 gallon tank should be 2.4 octane units if I did this right. Not bad. I I added this and drove a while...seems to be much more settled down. I should have logged it before but was just watching timing adjustments live with OBDEleven (VW scan tool) but will do some logs tomorrroww with the booster and see how different it might be. In the end much cheaper to add a few gallons of E85 here for $2.5/gal in the winter but figured I was at Walmart, screw it!
