Synthetic Oil interval?
Hi guys,
I decided to go synthetic oil this time. I picked up valvoline sythetic blend 5w-20 with mobil 1 filter at my local autozone for $21.99. I've been doing 5k oil change. I'm not sure if the interval for synthetic oil is more than 5k. |

Valvoline Syn blend I'd go 5k/6 months. Unless you have a nearly 100% highway driving cycle I'd go no further with that oil without a used oil analysis that included TBN. If your still under warranty I'd stick to 5k regardless.

after my oil analysis i wouldn't use 5w20. Don't know if its blow by from rings or what but my oil had a lot of gas in it causing the oil to thin out some

I would go at least 7,500 with a good wix filter. I went over last oil change and went to 11,000 miles and oil still at full mark looked ok too. Running Mobil1

I go 3k, but I get the 19.99 Mobil 1 gallon jug from Walmart and a cheapo fram filter so it's the same price as a regular dino oil change.

NA = Naturally Aspired, in this case stock FI = Forced Induction, boosted with either a supercharger or turbo

Although it seems odd thinner oil isn't necessarily "bad" where fuel is present and other factors about a chosen oil can be much more important than it's rated viscosity. My last report was about 1.6% fuel dilution. R2 |

Does it matter if there's some fuel circulating in the oil?

Even in a modern, fuel injected car there's always going to be some small amount of unburned fuel that makes it into the oil. Most all of this evaporates on a long drive when the engine gets up to full operating temperature for an extended period. But if a person rarely (or never) drives their car long enough for the oil to get really hot, then this fuel (as well as other contaminants) never gets burned off. The oil just gets more and more diluted by contaminants. This explains how one car can go 10,000 miles and its oil is still good, but another can go 2,000 in the same time and its oil is bad. |

Still need to stay with the 5,000 mile or 6 month interval to keep your warranty . Doesn't matter if it's conventional , a blend or full synthetic . Also keep your receipts of the oil and filter for records in case there's an issue .

If the fuel doesn't get evaporated out it can thin oil out, affect lubrication and create deposits. |
