[QUOTE="UnleashedBeast, post: 11404317, member: 112023"] As stated, fuel dilution is all in the tune assuming the piston rings are in good working order. Check out this UOA of Amsoil 10W-40 This car is 700+ RWHP with a built MMR aluminum 5.4L engine. It's a TVS setup with 18 PSI and tuned for E85. This was the second oil fill, break in fill was drained at 1,500 miles....hence, why wear metals are higher in the 5,000 mile sample. Getting to the point.... After 5,000 miles, note that fuel dilution is less than .5% and TBN is still strong at 5.3 The lubricants detergent additives were still suitable for continued use with very low/unmeasurable fuel dilution. TBN doesn't fight off ethanol, but on the flip side....this engine lubricant didn't suffer from ethanol if it was in the sump. Longer road trips probably evaporate ethanol just like moisture. [ATTACH=full]274281[/ATTACH] Diesel oils are not my primary choice to find lubricants that pass API SN certification standards, yet still have higher levels of ZDDP, and for three reasons. 1. Diesel lubricants commonly use magnesium and calcium as a detergent agent. Some tribologists have suggested that elevated magnesium ppm can cause deposit build up in gasoline engines. PCMO use primarily calcium. 2. Higher ZDDP doesn't always mean lower wear. I've noticed that lubricants containing lower levels of ZDDP, yet using moly and boron substitutes, having great UOAs as well. I'm still on the fence about high levels of ZDDP being a must for a street, non race car application. 3. You can see in the Amsoil sample above, higher ZDDP can be found outside of a dedicated diesel lubricant. You will also find high levels of ZDDP in Royal Purple HPS and XPR [/QUOTE]
