I'm going to switch to Delvac 1/Truck & SUV next change, and am wondering what everyone that is running one of these is doing for OCI's.





Thanks.

114 reads and no one is running Delvac 1 or wants to give me their input?

I started out at 5,000 miles then pushed it out to about 6,500 with the same analysis results. My next sample will be 8,400 miles, longer than I intended, but at least it will tell me something. All of these were w/o bypass filtration, which I installed this weekend. I expect 10,000 miles intervals as a matter of course after that. I might go longer depending on OA, but am concerned about the warranty issue.

Drop mine at 7500. Just can't make myself leave it in any longer. It would be a different story if I had bypass filtration...

I went 25k with an oil analyis that said good to keep going, I sold the truck so I don’t know how long it went.

I knew I wasn’t going to keep the truck do I figured I might as well experiment.

You know it’s funny, when you have to pay for oil changes the dealer says ( in general) 3k - BUT when I purchased a dealer service package with oil changes included they said I should come in at every 5k.

It is interesting that in Europe , oil is being changed after bout 12k kilometers, depends on oil and car, per the owners manual.

Here’s some fun reading
