VR1 is a great oil, but it is a non-detergent racing oil that is meant to be changed after a race weekend (or two depending on the engine), hence there is little need for the oil to contain any detergents.
Something to think about if you expect to maintain a normal oil change time interval while running it. BTW, we run Brad Penn 40wt in our Cosworth BDA race engine both out of experience and from the recommendation of the engine builder. Not knocking the oil that Jake developed one bit, because it's great stuff, but if Brad Penn is good enough for a 10,000 RPM race motor, it's probably just fine for our type 4's. |

Detergent, that's something I haven't seen advertised in a while so I got curious. Between our kids' three cars, our DDs, and the toys we have a collection of 7 oils in the garage at the moment, five conventional and two synthetic. They are all rated API-SN (except VR1) but none of them mention detergent, however, API-SN covers detergent qualities I believe. So I went looking at Valvoline's VR1 product info, see link below. They claim an API-SN performance level (though not certified) and recommend VR1 for street and track use. https://valvoline.com/pdf/vr1_racing.pdf I'm no expert in oils, but the in my opinion much of the industry is selling, and forgive the pun, snake oil. It is all so confusing, and from my research I've found many contradictory claims from labs or even contradictory product information from the manufacturers. And where is the empirical data? Outside of Consumer Reports many years ago, who has run a fleet of cars for close to 100k miles and tore all the engines do to examine wear differences? |
