Oil recommendation for high mileage Jeep G. Cherokee 4.7L with limited selection of brands and types

[Pudu4X4]

Hi, new to the forum,
I am not for the US, I am from Chile (South America) and I have a 2000 Jeep G. Cherokee 4.7L with 150k Miles in it, owned it for the last 2 years and doing yearly/5k miles oil changes. After reading and viewing a lot of info on this forums and YT videos, I am wondering if the oil I am using is good for an old high mileage car (Specially with the infamous early 2000's PowerTech 4.7 engine) so I am asking for recommendations.
I currently use Mobil 1 ESP 5w30, and there aren't High Mileage motor oil products or brands in my country.
As additional info, I use 93 RON unleaded fuel (88-89 AKI equivalent) and in my country the max sulfur allowed in gasoline is 10ppm. Is not a daily driver, I drive it 8-10 times in a month (most weekends).
Below I made a list of oils available in my country.

Keep using the oil you are using, excellent oil.

Easy.

All of the oils you listed are superior to the oil that was available when your Jeep was made. The Mobil 1 ESP is ideal.

I agree, I wouldn’t change a thing. Overheating is far more likely to kill that engine than any oil choice so keep the cooling system tip top.

ESP 5W-30 is one of the best you can buy. Better worry about the thermostat.

That's a good oil so you can keep using it. As long as it's getting something of ok oil and preferably on the thicker side and changed frequently you can't go wrong it's the cooling system that has issues. Some run a slightly lower 180f temp thermostat instead of 195f but any lower and the computer could have it running rich forever. If I had it I'd probably run 15w-40 and that's considering I can get ESP at my local walmart for cheap.

Thanks for the answers! Glad to know it is a good oil, I will keep using it.
On the subject of temp, I was thinking of doing a radiator flush cleaning and also checking the thermostat because of the age, but I don't know if I should as it doesn't overheat (temp stays ~210F). Radiator does have a really small drip from the top right side on the black plastic, dunno if change the radiator or just try a stop leak additive or something similar.

Perhaps start a new thread in the appropriate section of the forum.

Get a new radiator (Mopar is still the best) and HOAT coolant (Zerex G05).

Hello from your northern friends!

Awesome to see a WJ rocking it's way around Chile, it sounds like you're taking great care of it. Aside from oil burning, most of the complaints about the 4.7 are overblown. As long as you don't let it get hot, it'll just run and run. Our '02 currently has 187k on the clock and runs like a Swiss watch on whatever 5 or 10w30 I've got laying around the garage. It's never anything fancy and the engine purrs regardless of what oil's I've used. Stick with your 5k changes and you'll be just fine.

As for the radiator leak: fix it now. Do NOT use stop leak, just put a radiator in it. At this point that plastic is 25 years old, it's time for it to be replaced. I had to replace ours last summer, same thing: sprung a leak in the side tank from weak plastic. You don't have to use Mopar, it's not worth the cost at this point. I used the cheapest aftermarket I could find (they're all pretty much the same) and the fitment was very good.

Will look for a new radiator, if I have more questions I will open a new thread.

I owned 3 Jeeps (96 Cherokee, 99 Cherokee, 2007 Wrangler) with 4L engines. 195F to 212F is normal op temp for a Jeep 4L. 210-212F is ideal for good gas mileage and a clean engine. The OEM electric cooling fan in my Cherokees was factory set to turn on at 215F. I prefer to stay under 220F, but it's not overheating until it goes above 230F. My Jeeps never went above 220F in summer during moderate offroading. They never went above 215F in summer onroad. They were usually 205-210F in summer onroad, which was ideal for gas mileage, clean oil, and clean engine..

In all 3 Jeeps I replaced the 195F factory thermostat with a Stant 205F thermostat. This helped them run slightly warmer to get better gas mileage in winter and helped oil and engine stay cleaner. The summer op temp was not affected by 205F stat because in summer it'd run 205-212F regardless of stat choice.

My Jeeps were USA government rated to get 20 mpg highway. I got 23 mpg highway. The 205F thermostat made them run more efficient than with a stock 195F stat.

One of these Jeep engines lasted 410,000 miles without a rebuild. Motor oil brand/type used was nothing special. The other two Jeeps are still running strong with the owners I sold them to.

I think for your 4.7L engine 195F to 212F is normal (and ideal) operating temperature, most efficient for gas mileage, and will help keep your oil and engine stay cleaner. 220F or less is acceptable. You're not overhearing until it's above 230F. So relax. Damage doesn't happen until above 230F.

Cool engines (under 205F and especially under 195F) make more soot and sludge and get less gas mileage. Hotter is cleaner, more efficient, and won't hurt anything as long as it doesn't go above 230F. It's ideal to stay between 205F to 212F for efficiency and cleanliness, but up to 220F is fine. 230F is OK for short-term, but it's best to be under 220F most of the time.

I suggest NOT switching to a colder than stock thermostat. Keep using a 195F stock thermostat or another brand of premium 195F thermostat. You can keep using the same oil you currently do, but I prefer a Valvoline or Pennzoil synthetic if available (because they typically have slightly thicker viscosity than Mobil One which helps at hot temps). If your Jeep begins to leak or burn oil, then I suggest switching to Valvoline or Pennzoil synthetic blend 5w30. If those aren't available, then any brand of synthetic blend 5w30.
