The question that I can't seem to get a decent answer to is why so many racers use multi weight oil instead of straight weight. |

May I ask the part number of the Valvoline oil you refer to?
I have used the VV850 in the past but they no longer offer it. I believe they changed the formulation. Do you use an additive with the oil? ______________________________________ Andy Stone A/S 1102 SS/C 1112 |

The oil I used is straight 30 racing oil. It used to be commonly called VV223 but the Valvoline part number is 822401. Scroll down a little to find Valvoline's conventional oil part numbers, https://www.valvoline.com/our-produc...vr1-racing-oil
I don't use any oil additives. |

don't use either.
Been running Mobil 1 Synthetic 10w-30 in my race engines for nearly 3 decades. This past season switched to Lucas Synthetic. Have a case of Maxima Synthetic that I will run this season. |

The oil deal is a bigger issue for Stockers that have to use a flat tappet camshaft combined with high spring pressures and aggressive lobe profiles. For those not running under that set of rule constraints, there are dozens of oils that will work well. Excessive additive precipitation is something to consider when choosing an oil filter. Those dots can be connected accordingly. ![]()

Valvoline says that straight weight oils are usually recommended for smaller and older engines. 5th question down: https://www.valvoline.com/about-us/f...-viscosity-faq

This is a little off topic... but still oil related...
I've been hearing of some guys finding power on the dyno using some of the new oils designed for older Hi mileage engines. They say it is because the rings seal better. Anyone have any experience with that?
