I just started using mobile 1 in my rodeo on the last (actually my first for this vehicle) oil change. I have mine done at a shop since I hate laying on the ground in the parking lot in winter doing it, and oil changes just dont seem fun to me anyomore so I cant be bothered. What surprised me is the sticker they put in the window to tell you when the next change is due still says 3k miles even with synthetic. I'm not going to have it done till around 7k though, costs way too much with their mark up to change it so early.

I'm sure they did it out of concern for your vehicle. What possible other reason could they have? <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />

It's spring, isn't boat season coming up? Mmmmm...boat payment....better take it down to every 2k miles!

What's the difference between 1. and 2. ?
Does your 1. mean the mileage on the unit (engine)?
When I said service miles, I meant the # miles on the current oil sample.

Yes, they do want to know the type of oil, mileage on the engine, mileage on the oil, etc, etc, ... the more info you give them, the better they can relate your sample to relevant data.

In fact, you can (for a small extra fee) send them a sample of virgin oil of the type you are using, and they will also factor this in. If you don't, they will use the average data that they have in their database for your brand of oil.

Check out their website and look at some of the sample analyses they have posted.

I hadn't considered the "hobby" aspect... I guess I've got quite a few thousand dollars worth of "hobby stuff" around here that most ppl would consider useless, frivolous, etc, etc... <img src="/forums/images/graemlins/smile.gif" alt="" />

Thanks for clarifying. Yes, you're right, I thought service life was service life of the vehicle.
