2026 HEMI or Hurricane?

[HSKR R/T]

Love my truck but would never buy a Hemi again. If I go RAM again, it's the Hurricane.

-16 spark plugs
-F that oil filter
-F that fuel pump module
-Hemi offers two tick options..known problem... mine is passenger manifold..dont care if its a small percentage..they didnt fix it for years knowing
-I have to pray and change my oil more frequently and add lubegard hoping I dont get a $5000 cam lobe problem.
-less oil threads to spend hours on

Im getting old. Don't want to spend time skinning my knuckles on stupid stuff anymore.

Dumping extra additives in your oil is only going to help if you are using ****ty cheap oil. Adding extra additives to high quality synthetic oil can actually lead to higher wear levels.

I use Ultra Platinum and Lubegard. Lubegard is not going to lead to extra wear. It's been in my vehicle for 100K. Nothing wrong with extra protection. I also dont change my oil on the dot everytime. Gives me peace! I bought mine in 2020 when all we talked about was the hemi tick and how to prevent the cam lobe wear.

I chose the Lubegard with ultra platinum 5w 30 method. To each their own.

Well, it's good to know you have done the tribology research and verified the additives in the Lubeguard are compatible with the additives in the PUP. And yeah that's sarcasm, because you probably just read the bottle of Lubeguard, bought into the marketing, and just dump it in

 

[kdoublep]

Marketing? I got all that knowledge here through some very knowledgeable members. You've been on here for years so you should know. You can disagree with me but dont be drinking your hater-ade cuz you're bored.

I'm not against additives as a whole, but considering that LubeGuard was actually made primarily for transmissions, I can't help but question the validity of it being used in a crankcase...especially since you're already using a top of line oil...a thicker oil at that. So it comes down to this: what does LubeGuard actually have in it that the ultra platinum lacks?

 

[kdoublep]

It mainly adds Esther film strengths which PUP has but in smaller amounts so it is a good compliment.

Thanks for sharing! Its been in there for a long time and if my engine fails due to Lubegard, I'll post it here. So far so good.

Understood. I'll look into it a little more.

Do not waste your time or money. If you are using good quality synthetic oil, there is absolutely zero need for any extra additives that may conflict with the additives already in the oil. Plus it changes the viscosity.

This.

I started using Mobil 1 oil in my vehicles in the early 80s. For the most part I have stuck with it over the years except for a few years when I was using Redline synthetic in some BMWs I had. I have never used additives and never had an engine die on me from oil related issues. I've gotten over 200k out of Chevy V6 and Chrysler V6 and both engines going fine when the vehicles died from other reasons. Throw in at least 4 or 5 more engines I've gotten over 100k with no issues. Use a good synthetic oil and a good filter. Change your oil every 5k and you're good to go.

Personally, I don't like oil additives in general. However, I want to clarify what you said about it. Lubegard is the name of the company. I'm assuming the product Lubegard makes that @kdoublep is referring to is called Biotech. Lubegard started out developing additives for automatic transmissions, but now produces additives for more than just transmissions. Such as cooling systems, power steering systems, and differentials. Biotech was developed for use in engine crankcases.

From what I remember reading about it a few years ago, many people use Biotech because it contains quite a bit of moly, which is somewhat lacking in many motor oils. Some people claim that it's effective at quieting their Hemi tick. There are threads about it in other Ram truck forums, as well as a well known oil forum. I don't see a need to use an additive just to increase moly when I can just use a motor oil with a higher moly content, like Redline.

My own oil additive experience goes back more than 50 years when, I was a young, poor man in the U.S. Army worried about his AMC Hornet six cylinder engine. The engine was fine as it was. And new. Only 10k miles approx, we’d bought the car while I was in RVN.

I saw ads on TeeVee hawking STP oil treatment in a can. A thick syrup that poured in slow. A few thousand miles later I realized the engine was burning oil and fast. All six cylinders showed signs of excess oil in the chambers. Didn’t take me long to blame the STP.

My 2 cents says the straight six with 2 turbos will never out last the N/A V8. A turbo six has to work harder to do the same amount of work as a v8 period. Your internal pressures are way higher so wear will be greater and internal clearances are more critical. I say the Hemi if you plan to get more than 100000 miles out of it.

Being I currently own a 2023 Ram Hemi 5.7, I thought that my next Ram would probably have the Hurricane. But I'm starting to think that may be a 6.4 Hemi in a HD, made to last, would be a better choice. Could also be my current truck, my almost three years old 5.7 is running like smooth silk...knock on wood lol

You would be wrong about the I-6 working "harder" to do the same amount of work. The Hemi needs higher RPM to be in its powerbanf. Trans will downshift quicker to get RPMs up to maintain speed.

The Hurricane is built to handle boost. There are stock long block HO Hurricanes making 1000 rwhp is vehicles. If anything the factory tune on the Hurricane is very conservative and it's no where close to its max potential. But since it still has to meet EPA and CAFE standards, they can't really crank it up too much.

There is a reason they stopped offering the 5.7 in the HD Rams. It just didn't make enough power to handle heavy towing, so they switched to a detuned 6.4 that made more torque.

This assumes that the I6 wasn't designed as a turbo application from its conception and is no different than saying fords coyote 5.0 V8 would never last as long as a 5.7 V8 because the stresses are more on the engine due to its size. Your hypotheses doesn't factor in increased bearing size for the loads, forged internals for the increased load, internal support in the block for the increased loads and only relies on the physical size and configuration of the engine being the limitation.

What truly causes engines to prematurely fail is high RPM and constant high RPM. The Hurricane makes more power at lower RPMs than the 5.7 HEMI or in other words, the 6.4 and 5.7HEMIs need more RPM over a longer sustained period of time to complete the same work.

Not trying to be a donkey but there's no mechanical logic to your reasoning in the above statement. Many V6's and I6 have been making V8 level power for the last 20+ years

The only things adding stress to the I6 is the forced induction towards the cylinders and valves really. The engine itself doesnt work harder, in fact...it works less than a V8 because the high RPMs are not needed. But if all of the internals are manufactured to handle at least twice the heat rating of what the turbos can dish out...theres no reason why that I6 can't last as long as the V8. Carbon build-up is my only concern without the port injection though (which i mentioned earlier)

Higher RPMs doesn't mean the hemi is working harder than a forced induction at lower rpms. 30 psi of boost is a huge amount of stress on an engine. As for the bearings, high load at lower rpms is absolutely terrible for them.

You cannot deny the facts man, those hurricanes are highly stressed. What's less certain is how well they will survive vs the hemi, but Ram engineers are not putting hurricanes in 2500's for a reason, and yet the 5.7 was used for years as the base engine. The hemi was built in a different era, when engines were all cast iron block and meant for heavy duty. The hurricane is a passenger car engine meant to squeeze out every ounce of power out of a lightweight, low cost engine with low emissions and higher MPG.

Hurricanes also use spray on cylinder liners that become like paper and delaminate if they overheat, and any possible damage to them means you can't repair them easy etc.
