Got it done. Now, i`ll send a sample off to Blackstone to figure out my oci. Iv`e been stuck at 3000 miles my whole life. Maybe it`s time for a change? Still won`t be 7500 to 10,000. I`m much too hard headed for that. Been in the mechanic business for too long. Have built too many engines that we tear up. On purpose, of course.

I like every 5000 miles. Easy to track and less than the synthetic oils are rated for and right between the 3000 and 7500 that are generally recommended from oil change places and the owners manual respectively.

If have any kind of warranty and you do your own oil changes make sure you keep receipts for the oil and filter. If you need warranty work and don't have them some dealers will void your warranty.

Curious about how you all get under the truck. Can you just crawl under or do you need to lift it. Do you use ramps or jack it up and use jack stands? When I lived in a neighborhood with curbs, I could drive up on the curb and, using a piece of cardboard, slide under my car. That was a long time ago when I was a lot more flexible.

Plastic Rhino Ramps for me. Light and easy.

That mileage as an oil rating is marketing, not science. The OLM ditto.

Just looked it up in THE book. Says use the OLM as it is "programed' to calculate oil life based on usage factors (unlisted). Then says if it is reset accidently 3,000 miles. Both normal and severe schedules say 7,500 miles. Now that should ring a few bells. I have 185,000 miles on mine and no matter how I use it it is programed for 7,500 miles. They thing not getting caught in a lie is the same as telling the truth. :banghead: I change my boutique oil at 5K.

I found out recently that the OLM in my new car can be user set anywhere between 4K Km (2500 miles) to 20K Km (12K miles). Depending what market it is sold in and what regulations are in play the oil recommendations run from 0W20 to 20W50.
