2.0 turbo longevity questions

[TheRaven]

Vehicles built as of today, are at risk for some expensive failures. There are many reasons for this, poor quality, massive amounts of electronics, Federal mandates pushing fuel economy to the limits, along with a reduction in emissions, and the list goes on. If I was to purchase a new vehicle today, which I am not, I would buy the most extensive extended warranty insurance policy available. Or only keep it, until the original warranty was about to run out.
The above statement was not only referring to Jeep vehicles, buy applied to all Brands of vehicles.

This is great advice for almost all modern vehicles, but ESPECIALLY for FCA products.

Yeah, the rational side of me says dont keep past the extended warranty. The dream is a forever jeep.

Any thoughts on techron fuel cleaner every 5 k?

Hey, I'm considering a 392 2024, but used with 2500 miles, they are offering a free 7 year 100,000 limited powertrain and CPO, any insight on that, sounds like I still need a max care 5 year 50k?

It depends on your wallet. Last year I bought a 2019 Rubicon used with 33000 miles. 9 days after I had it the 8.4 in radio fried and it went in to a boot loop. A new unit was almost 3500 dollars. Dealer tried to say Maxcare wasn't in effect yet. I said fine, it's a CPO and has a 90 day bumper to bumper warranty. They fixed it, scumbag charged me 100 dollars, deductible they claimed.

I WOULD NOT OWN A JEEP WITHOUT MAXCARE.

fwiw

For those who have it, how much is MaxCare? I know the repairs can run high, but what about the cost of the warranty? Still in year 2 on mine, so have some time, but want to be prepared.

i looked on website for a 5 year 50,000 mile and it was about $800 for a 2024 392.

Project Farm on YT compared Seafoam and Techron. He’s pretty thorough. The oil testing is…ok but not a full picture. Anyway, they both barely helped remove deposits. It’s about preventing them in the first place and running a top tier rated fuel. It won’t hurt to run Techron additive here and there.

I have used it for many years, in our vehicles. We have never seen a fuel injector fail. It is the only additive that I use!

I know the local gas stations around me that have top tier and stick to those (mostly costco). Checked 2 days ago, premium non ethanol was exactly $1 more per gallon.

I do about 15,000 miles per year. At 20 mpg, that’s about 750 gallons or about $750 per year to run that. With 8 year warranty, it'd be about $6,000 more to run premium non ethanol (just ball parkin here). Thatll pay for a hefty enigne repair if

Ive been on the fence about this. Im just such a damn cheapskate with the gas.

i have not heard any knocking or pinging.

I did find this little excerpt in the owners manual:

Indiscriminate use of fuel system cleaning agents should be avoided. Many of these materials intended for gum and varnish removal may contain active solvents or similar ingredients. These can harm fuel system gasket and diaphragm materials.

Granted, it does say indiscriminate use.

I did run a can of Berrymans B12 through the tank which ends up decently less concentrated than what Berrymans says you can use IF you fill up the tank. I think they and Marvel Mystery Oil?…not sure, are the common solvent based (most aggressive vs Seafoam and Techron) fuel and oil additives. That was after about 95k miles and only did one can to a full tank. I tell ya though, I felt a responsiveness difference after less than 100 hwy miles.

Will not do anything useful in my book. Fuel contain de-gummers and detergents etc already. Has some potential for harm.

The only advantage using ethanol free gas is that you'll get a slight mpg bump - around 3%. I use it at times in Utah if the price is not much higher.

...and avoiding accelerated deterioration of non-rated fuel lines*, as well as ethanol deposits in the bowl if one's use case includes carburetors. Mine does, via one of the two motorcycles and all of my OPE. Being forced to strip and clean a carb of accumulated hard yellow build-up serves to concentrate one's mind on the subject. I now keep a rotating stock of 30 gals. of E0 in the shed to keep the relevant machinery happy.

*Ethanol being a solvent

Cars has been designed to run E10 for how long? 20 years since MTBE was phased out? There's no harm running E10 on your Jeep. I run long term tests with up to E80 on vehicles.

When I was researching prior to and immediately after buying it in 2020 JLU 2.0 Sahara there were two things that stuck out:

1 - when it's hot out, and you plan to tow - throw in some premium (or at least regular plus). I have towed multiple times and while I can't say I heard any pinging, it just felt better after throwing in premium. (picked up the trailer with 1/4 tank of regular then filled up 15 mins later with premium) The timing adjustments the computer makes are real and can add up over time if you don't.

2 - The biggest concern I found about longevity of the 2.0 was the gumming up of the intake valves due to blow by from the crankcase venting system. I now have 77k KM's on my JLU and I still haven't purchased one of these...the last time I looked they didn't have one that worked at higher altitudes without throwing CEL's and I live in Calgary, AB Canada which sits at about 3500 ft above sea level: https://www.mishimoto.com/jeep-wrangler-2018-20l-baffled-oil-catch-can.html If you don't live at higher altitudes this could be a good investment?

At the time (about 4 years ago) there wasn't much info out there on point 2 above, but maybe others on the forum have some experience with this now?
