by experience, if you change oil 3-4 times a year.

you could buy any oil on sale & won't make a difference.

is there any way to tell what kind of oil I have? synthetic or dino?

the guy I got mine from lost his job (seaplane pilot - long story) just after the jeep got on island. he had no money to anything with/to it. it was driven about 15 miles a week just to keep everything "working". he had no idea the type of oil used and unfortunately there are absolutely no service records. what's a poor boy to do?

next week the 60K service and complete fluid flush is scheduled. I really don't to mess anything up and end up trashing my engine.

Don't worry about what oil is in there now, synthetic and conventional are completely interchangeable (mixable too) and you can switch back & forth without any problems whatsoever. There are way too many false rumors concerning synthetic vs. conventional that get repeated until they seem like the gospel.

You know what you get when you mix a 5W-20 Synthetic with a 10W-30 motor oil? A 7.5W-25 Blend that would work just fine.

Im glad you said this Jerry. I have thought for years that you couldn't switch from synthetic back to conventional. Now that I've actually looked into the matter you are completely right... As always

Of course you can switch back and forth from conventional to synthetic. Companies produce synthetic blends which many people use. Those are literally synthetic oil blended with conventional oil. If you can put both in the car at the same time, you can definitely interchange them.

And just my .02, but if you are using synthetic oil and still changing your oil every 3500 or 5000 miles, then there is no reason for you to not use conventional oil in the first place.

I was actually just discussing this earlier in another thread but i dont judge oil changes by mileage. I judge it by when the oil gets dirty. Unless the vehicle is sitting alot and then i will change the oil at 6 months to keep everything running smoothly

I've heard that as well, but experienced the exact opposite. When i picked up my Jeep, used, it had a slow rear main leak. Maybe one drop every couple hours. I used conventional 10w30 for the first oil change to get a baseline, and so no change in the drip frequency. I switched to M1 synthetic 10w30 for the next change and the drip slowed down to one or two a day over the course of a couple weeks. 2 years later sticking with M1 synthetic and it'll leave a parking space dry for a week at a time.

I'm not saying that the switch definitely caused it; maybe a piece of crud broke off and gummed up the leak or something, but I'm happy not to have to do a rear main job now.

Gotcha. Using the oil as your guide and not mileage, how often would you say you wind up changing it?

Well i just switched from conventional to synth so this will be changing but between 2k and 4k depending on how much offroading and dirt road driving i do. I would guess i will be changing ever 6k or 8k now.

Just a personal opinion.

The reason why I change my oil is to remove impurities from the motor like fuel and moister to name a few. It was my understanding the reason why synthetic oils last so long is because it keeps its synthetic state by not mixing with impurities where a conventional oil will absorb and mix with unused fuel and moister in the crank case and drain out with the oil during an oil change. I was an ASE Certified Automotive Master Tech and its surprising how little I know about lubricants. I did work for and was a mechanic for Fedex, 16 years. Fedex used conventional oil we got 250,000 miles out of our gas vehicles with 5k oil changes. If there was any value in synthetic oil I'm sure Fedex would have used it?

One time back in the 80's I was in a motor that supposedly the owner always used synthetic oil? The oil looked great, but the inside of the valve covers were coated with a gooey oily substance, maybe the impurities that should have drained out with the oil, who knows?

Use a good oil, filter, and change it often and you will be fine.

I am thinking about changing the front and rear diff fluids with a synthetic on my 2014 Unlimited, but conventional oil everywhere else.

Not so much an opinion as possible facts lol just facts that I have never heard. Is that really the reason why synth lasts longer? I thought that it just took longer to breakdown and therefore was able to stay clean and good for longer?

I switched all fluids (oil, dif, transfer case, transmission) to Amsoil Synthetic. Everything runs much smoother than prior. And my Rubi only has 24k miles. Never thought I would actually notice a difference.

I bet I could sneak in at night, switch all your Amsoil lubes to Castrol, Valvoline, Mobil, etc, and you never notice the difference afterward.

That may be very true! Please do in about 9 months when it's time for an oil change

It only stands to reason that there are different wear and heat, patterns between lubricated parts when different lubricants are used. Just plain water is the best lubricant there is but if you use it, and then go to oil or synth, problems arise. Go figure! :-(

Synthetic is the way to go. Jerry is right about conventional oils being better than ever. But in my experience synthetic is better. It does not break done as fast. It handles heat better and the viscosity is superior. Can you put 300,000 on your engine with conventional oil? Of course you can. Regular maintenance and treating your engine right goes a long way. All my vehicles deserve synthetic and that's what they get.

If you decide to switch to synthetic at that mileage, make sure you do the following BEFORE the switch:

change oil pan gasket
change valve cover gasket
change rear main seal

I changed mine to synthetic (1999 TJ 2.5) at 82k and ALL of those started leaking before the next oil change was due. Bleh.......

It doesn't run any better or worse, it doesn't have any more or less power, it smells the same, and still does not fix itself so I think it's not worth switching.
