Why did Jeep change their recommendation from 2012 to 2013 from 5W30 to 5W20? Did something change with the engine?

I sent a e-mail to Chrysler/Jeep tech support and asked that same question. When you use this site you receive a automated response back immediately. It tells you that they will respond back to you within one working business day. That was over 30 days ago and still no answer. I have called their technical support twice and they didn't have a answer for me as to why, or why no response to my e-mail question.
This is obviously something that they don't want to answer.

Not offended, but I like to joke around and there are some folks who don't take it well. Just saying in case you were one of those who gets their feelings hurt by my jokes.
Besides, you don't like synthetic oil so that's already strike one.

O.k., I just called Technical support for the third time and talked with a representative by the name of Raymond.
I gave him my e-mail Ref number and asked as to why I can't get a answer to a simple question as to why viscosity change.
He is going to take this up the ladder and get me a answer, by no later than Tuesday of next week. We shall see if it happens.
This thread will probably be down the ladder by then, so if I get a answer I will post it on a new thread.

I know, the story of my life, strike three and I'm out......I think that is what all six of my wives have told me. In other words, if you strike out, then you are a loser!
But I still want the Spurs to win.

Wow, so you've been through at least 6 trailers too. At least they let you keep the jeep.

They took my first two a CJ5, and a TJ, but this JK Rubicon is out of their reach! It's in my Will, that when I croak, it must be buried with me. So legally it's hands off to them........

Simple. Proven to have better protection and I can change my oil every 10k. I just turned 100k , 10 oil changes and all is good.
I use mobile one 5w-20 and a wix extended length filter.

Synthetic only and 5W30 only. Currently using Pennzoil Ultra. I use others on the 4Runner (German Castrol mainly) but Chrysler-spec oil in the Jeep. I like Ultra the best but would use any decent synthetic. I change oil myself.

So after my initial post ive been watching this thread, i cant believe the amount of synthetic cool aid drinkers out there lol. Im not putting you guys down or anything your gonna do what you feel is right for your rig but i believe it is a waste. Cars were around for roughly 65 years before the first synthetic hit the shelf. Heck i had a 4cyl ranger with over 200 on the clock and it ran a quart low on dino most of its life lol. Almost none of you will see the benefit of using synthetic oil. You wont have your rigs that long or crack open your motor to inspect the cylinder walls. Even if their is one to truly be had at that. What bothers me the most is these crazy drain periods you guys are talking about, 10k miles is just crazy to me no offense. Idc if your using angel tears to lube your motor, it shouldnt stay in there that long. Its like using the same piece of tp over and over again. Could it do the job? Sure. But just throw it out and get a new piece man its dirty lol. You cant take an oil and say its great just by its ability to resist breakdown. Sludge resistance, cleaning abilities, additives and a whole bunch of other stuff incant remember are all things to take into account. Put a premium conventional in it, change it every 3k and be done with it. Ill say again, todays Premium conventionals are on par with synthetics.

I agree the modern conventional oils are almost as good or close enough your never going to see the difference . But I do think longer service intervals are doable. I feel ok going every 5k miles on a wix filter and some good dino oil or even synth if im feeling spendy.Running a wix filter and Penzoil ultra this time as wally world had it on sale.

I ran a 95 YJ 2.5 285k miles on castrol gtx and wix filters and it still ran strong and didnt use a drop of oil when I sold it.Did 5k mile service intervals.

Valvoline Premium Conventional 5W-30. It has a better cold temperature Pour Point at -42C than some of the "synthetics".

A little secret: There's synthetic oil in the major brands conventional oil. They aren't going to tell you because then you wouldn't pay more $ for basically the same product. Found that info in a Jobbers World newsletter about a year ago.

Another little secret: If you want to get rid of contaminants and condensation in your oil, change it and don't leave it in there for extended periods.

Oh yes, take a look at Castrol Edge with SPT syntheic 5W-30. Its Pour Point is -39C, not much better than their GTX conventional oil. Valvoline Premium Conventional rules. Well, maybe it doesn't rule but your engine will outlast the rest of the vehicle if you use it and change it about every 5,000 miles/8 months, depending on driving conditions.

Why would anybody, that only plans on keeping your wrangler for three (3), or four (4) years, which is common for a lot of owners, ever spend all of that extra money for synthetic oil, your are just not going to get a return on your investment.
For those of you, that say, well we will run longer oil change intervals, well you had better read your Wrangler owners manual, before doing it. Chrysler/Jeep so states that synthetic oil is acceptable if it meets the oil requirement guidelines and our oil change interval guidelines. So no, there is no savings there!
Now for those of you that are planning on keeping your wranglers for 10, or more years and also use it as a daily driver, and are trying for the 300,000 mile target, well then synthetic, may extend your engine longevity to hit your target, but even that is somewhat questionable!

I use ZMax...because the NASCAR commercials told me so.

But seriously, I run Castrol synthetic and change my oil religiously every 2,000mi because I firmly believe I get an increase in HP...

Its a forum about motor oil, learned a lot from those guys.
I recently had a problem. I recently purchased an engine oil and that made my engine go worst of its performances. Someone told me that there are huge number of vendors supplying adulterated engine oils. So how do i differentiate between the original and the adulterated ones. Please advise me.

I choose my oils on taste alone, the saltier the better.

I would sample it, and if it leaves a bitter taste in your month, then don't buy it.

I'm no mechanic but logic seems to point me to believe that more frequent changes with conventional oil > less frequent with synthetic.

IF I gave you the option of applying 50SPF sunscreen 1 time, or re applying 30spf throughout the day at the beach, which do you think will keep you from getting sunburned?

Oil, dirt, contaminants, etc. Eventually get into the oil. Period.


The Oil issue is so funny to me. I think people get confused by all the numbers and differences and it scares them into thinking there's some ocean of difference between different types of oil.


The truth is there is no evidence that running synthetic will give you longer engine life or any of that crap. Any story you hear about that is anecdotal at best. 586 other factors also influence engine life.

Guys argue about this on my motorcycle forum also and some of the ones who have been riding, working on, and around motorcycles the longest swear by the cheapo walmart rotella for diesel (technically called a "synthetic").

You who are wanting to spend the extra money on synthetic - seems to me you might as well put super premium gas in the Jeep, another splurge on which you will see zero benefit.

For most of us, we either have the 25 HP 3.8L pushrod engine, or the SLIGHTLY more technologically advanced 3.6L. These are not high compression, high revving, forced induction race engines. Most of us never get near the red line.

When I buy my 2013 Lamborghini Aventador I will probably run the best oil money can buy in it.
