first oil change

[darmano]

I changed the oil at 2500 miles and installed the Stahlbus oil drain valve

Do you know what size you bought? there's a few options on Amazon.

Be really careful with that drain valve off-road. Would not be hard to open it on a rock and dump all your oil...

Not sure these oil drain valves are a good idea if you plan to off-road the jeep. You could open it dragging on a rock, dump your oil, and severely damage your engine.

Very, very true.

my 2 cents, my last 4 cars and my 911 and Harley all run synthetic (initial fill), I follow the manufactures recommended oil change intervals (or once a year in the 911 since I don't put many miles per year) on each vehicle, 3 of the cars had over 120K miles and never used a drop of oil between changes and no oil related problems, trust the engineers that design and test your vehicle, thats what your paying for. remember when Mobil 1 recommended 25k miles oil changes? That was on motors that had tolerances that were not even 50 percent of what they are now, your call, do it if makes you feel better, but there really is no reason to "over change your oil". anymore....

I get where you are coming from, and I don't think you need to change it every 2000 miles like the old days, but new engines breaking in can get some metal in the first batch of oil. And all engines get some grit and combustion by-products in them. Plus, before you trust the manufacturer blindly, consider that a lot of incentives have changed since marketing required them to offer free oil changes for the first few years. How do you manage the cost of that program? Fewer recommended oil changes. Plus, publications compare the "cost of ownership" for new cars, which gives an incentive to make yours look cheaper by requiring less service. And there is the fact that consumers don't like to have to go into the dealer for service. Combine all that and you are looking at some powerful incentives to push recommended intervals up. So I take them with a grain of salt myself. I am probably over cautious because I like to have the option to keep a car for a long time if I want to, but for my vehicles, I've tended to use synthetic only and just change at 1K then at 5k, and every 5k miles after that. But that's just me - every one needs to do their own thing. If I leased vehicles, I might not be as proactive, for example.

0W20 is synthetic. Of course, that word doesn't mean much, since virtually all "synthetics" come from petroleum base stocks before the pixie dust is added. :cwl:

What do people think about that 0W-20 recommended oil? I have heard that it is very thin and designed to prioritize gas milage over engine protection. Some seemingly knowledgeable folks say that 5W30 synthetic is as low as they go, and they cite oil analysis results showing more wear with the 0W20 to back them up.

I made this exact point a few weeks ago. The longer intervals have occurred from a marketing stand point and competition among manufacturers. I know from first hand experience.
