Which Engine oil do you use??

Hi Guys,

I have 2003 Rubi - 29,000 miles on it. Is anyone using synthetic oil in their engine? What weight of oil are you using? I am in Southern CA - Hot Hot Hot so cold morning starts are not an issue here. I wheel in the desert - slow stuff and some city traffic.

I run conventional. 10W-30 I think? I've used both 5W and 10W in it, and haven't seen any ill affects yet. I also have 60k on the clock. In addition to the oil I only run 5 quarts oil and then 1 quart Lucas Oil Stabilizer.

I run Mobil 1, I live in the central valley and it gets hot here in the summer and cool in the winter.

When I bought my Wrangler I did a lot of research on what oil/filter to run. Previously on my XJ I was using Valvoline MaxLife oil with a Fram Tough Guard oil filter.

Update: I no longer run Mobile 1 10w30 and will be switching to a 10w30 with ACEA A3 ratings after reading "My oil is killing my engine!" thread.

I eventually decided on Mobile 1 10w-30 full synthetic paired with a K&N Performance Gold oil filter(The 1” nut on the filter makes oil changes easy. I also like that K&N uses an anti-drainback valve). This is for a 2006 Wrangler Unlimited with 32,000 miles on it.

I run Valvoline (dino) 10W-30. And in 45 years of driving and using nothing but dino oil changed every 5K miles, I've never had an engine failure.

Personally, I wouldn't pay extra for synthetic except during the winter if I lived somewhere like Buffalo NY or North Dakota where it gets cold enough to take advantage of synthetic's better cold weather flow. Synthetic is certainly not the miracle lubricant many think it is. Heck there's a guy over on JU whose 2.5L engine just crashed and burned after only 111,000 miles and he had run nothing but synthetic oil in it since it was new.

If you've got a Napa near you, get their 10w-30. It's good stuff, basically the same as Valvoline (as far as I can tell). Bang for the buck and all...

You have a 2003 with very few miles on it. I personally would run synthetic in your case. I run dino in mine and typically tell everyone else to do the same. Since you are not putting anywhere near 3000 miles in three months synthetic may save you money. The synthetic would have a 12 month shelf life inside the motor.

Jerry, the OP in the link you posted had a 4banger that went TU, not the 4.0 I6.



To answer the original question, I use Valvoline Synpower 10w30 in all my vehicles. Always have.

I know a lot of people think synthetics are great and all, but:

Your jeep engine was designed and tested using conventional oil, it has never been tested with synthetics that I know of.

So, if it was designed and tested to last 150k miles + on cheap oil, why would you spend all that money on synthetics?

I think maybe BMW and a couple of others actually design and test with synthetics but not jeep.

Synthetic oil is better under extreme conditions. How much better is debatable.

I use Mobile 1 10W-30 - high mileage, so I get the zinc levels needed for the flat tappet cam.

I require things to do.

Here comes the oil debate again. Conventional Valvoline 10W-30 is in the pan right now, but I might change to Rotella since it's heavy in zinc and I have a source for it that can save me a dollar a quart below retail.

If it's worth doing, then it's worth overdoing.

I use the cheapest brand name 10w30 and change it every 3000 miles for the past 100K miles. I'm at 166K and counting.

Cheapest 10w30 here as well. About to break 200k and the engine still sounds as smooth as rocks in a dishpan.
