I also agree with the posters saying Valvoline needs to change their 3000 mile OCI recommendation.
@5qts per oil change
Valvoline Nextgen at 3,000 OCI, you need to refine 10 quarts of oil, and you also are using the same amount of virgin oil.
Any quality synthetic, Mobil 1, Synpower, Penz Plat, etc. you can run a 6000 mile oil change comfortably, you end up using the same amount of virgin resources. Howerver, you SAVE ENERGY because 5qts worth of refining energy has not been used.
Finally, if there is a 5k recommendation then you will have an environmental impact. At a 3k oil change interval though, it's just taking advantage of a green market and Valvoline knows they are [censored]'ing customers!
Overall, the benefits of running it for a 5k, perhaps a 6k, OCI and the energy saved from refiners is worth it; the market share of recycled oil needs to increase and then other big players will join in. Hopefully, Mobil and Castrol hop on the bandwagon next.
