Havoline vs Mobile Clean 5000

BTW, what's so magic about a Hemi, anyway?

"The new Hemi is immensely popular.
In 2005, the total Hemi engine take-rate was approximately 45 percent on vehicles offering the engine. In some cases, it appears to be the main reason why people buy the car or truck around it.
The new Hemi produces roughly (it varies by car/truck) 345 horsepower and 375 lb-ft of torque from 5.7 liters when used in the Dodge Ram - one horsepower per cubic inch.
In the Charger, 300C, and Magnum RT, it produces 340 horsepower but 390 lb-ft of torque - an odd reversal of the way things usually work: trucks are normally tuned to have lower horsepower and higher torque."

I'm a Jeep guy and try to keep up with the latest junk about the new Wrangler (it MAY not even be called that!). Word has it the Wrangler will get a 3.8L (slightly bored 3.7L) V6.
I hope they stick the 2.8 CRD 4popper in there for some nice low end torque, seeing as how the "real" jeep engines are going(or gone). Can you say "soccer Mom" takeover...

Either way, I've seen a couple of spy shots of the 4 door Wrangler and it looks more street oriented with a vulnerable "B" pillar and low ground clearance. I won't be getting rid of my "mostly" '92 YJ or '59 CJ5 anytime soon.

BTW, I've been president of a Jeep club and am part of an association with several hundred Jeepers. I know quite a few with several hundred thousand miles on their 4.0Ls. I remember one guy asking me what he could do to get a little more power from his 2.5L (which I have in my YJ). I asked him how many miles were on it...he said, "oh, 220,000 miles". Jeebus.

Thanks to all for your comments on my post. I will try the Clean 5K in my wife's Malibu Max LT. I'm currently up to 168 qts in my stash, so whats a few more?

I heard that they brought back the main designer of Chrysler's famed slant six to oversee the design of the new Hemi. I also hear that it is cheaper to build and install than the V6's which are the alternate engines for these vehicles. They are also made in Mexico.

Markc-Note that I said *most*. I have seen higher mileage ones come through. No argument there. Most 4.0 major rebuilds I have done stem from excessive piston clearance and bad rod bearings. Most top end rebuilds are for worn guides, trashed lifters and the occassional worn rocker. Some 97s were plagued with weak valvesprings-seen some of them come through too. I've seen some really sloppy timing chains and junk oil pumps as well. I'm not going to say where I work, but I see more Jeeps than the average person will ever see.

Right now my 97 4.0 has some real bad piston slap and one or two of the lifters are getting loud. It only has 93K and some change on it. Not exactly a high mileage example by any means; this one surely isn't going to make it to 200K before it gets pulled apart. I'm making plans to replace it with a 4.6. My 98 4.0 has piston slap too, but not as bad and it has 112K on it. I'm going to let this one go as it's got so much body rash that it's not even worth rebuilding.

You can't be serious about the Hemi question. If you haven't been coherent since 2002, the Hemi is Dodge's crown jewel engine-for the 2nd time now.

The SRT Grand with the Hemi has 420hp and 420ft/lbs. Sweet Jeep even though it's geared towards street use. The Hemi is "modular" in the sense that it can be detuned to fit the performance needs of say a Wrangler. I'm not saying the new Wrangler will see it, but I would be very, very surprised if it doesn't get a version of the Hemi eventually. The marketing power behind the Hemi name is very powerful and it's already been proven that people will pay high $20s/low $30s for a Wrangler because look at all the Rubicons Jeep sold. Expect the Hemi to carry a premium price and expect all of them to sell-if they build it. Peace. And keep them 4.0s running.

One of the reasons (and there are a few) DC got rid of the inline 6 was the lack of modularity of it. In English, they couldn't use it and weren't using it in any of their other models...the only platform still using the inline 6 is the TJ Wrangler. That's pretty much the reason why the new and improved 07 Wrangler will have a modular engine that is shared with another platform or platforms. There are other reasons for the death of the 4.0 that I have mentioned in other posts, but this was probably one of the biggest from a $$$ standpoint.

edit-I find it funny that the Wrangler platform has been the "coffin" per se for retired veteran driveline parts. First, the old TF 904/999/32RH 3spd trans was killed off while being used in the Wrangler and only in the Wrangler at the end and now the 4.0 has been put to rest in the Wrangler.

Where can I get Exxon Superflo for 65 cents per quart? I assume there is a rebate involved?

 

[Slick17601]

If Superflo is the same as Clean 5000 why is it only SM rated while Mobil Clean 5000 is rated SM/CF. I think the diesel rating gives Mobil the edge.

"Exxon Superflo is 65 cents after rebate and its the same oil as Mobil 5000"

There is another grade of Mobil, Mobil Clean. It's their bulk oil. I seriously doubt Superflo is Clean 5000. My guess it's the regular bulk Clean...same as the old DCO...yes? I did not have good experiences with DCO, it burned off fast, but I shoulda probally been using 10w-40 instead of 5w-30. Anyway, Clean 5000 is not the same as Superflo until there is a VOA that shows the Sb.

What are you doing to your engines to wear them so quickly?

Where do you live (winter / summer temps)?

What grade oil do you use (winter / summer)?

Do you drive your car up to freeway speeds right after starting it cold?

Do you hot-rod a lot?

How frequently do you change the oil?

Just curious.

What are you doing to your engines to wear them so quickly? Absolutely nothing. Jeep had a piston slap issue with the 4.0s before they "took care of it" in late 99/early 00.

Where do you live (winter / summer temps)? Live in the upper midwest. Temp ranges from -20 to 90+.

What grade oil do you use (winter / summer)? Used to use Mobil Delvac 1300 Super 15W40 in late spring & summer and Castrol GTX 10W30 in fall & winter & early spring. Now I use Mobil Clean 5000 10W30 year round. Oil filters have always been Purolators/Motorcrafts.

Do you drive your car up to freeway speeds right after starting it cold? No. Engine is up to ~210 well before hitting the interstate. These days the Jeeps hardly see the highway. Just all local driving.

Do you hot-rod a lot? No. Neither has been redlined.

How frequently do you change the oil? Every 3000 since day one.
