Re: Wk2 hemi oil change

So this engine is running on conventional oil. My 06' 300C 5.7L had always been synthetic. I've read numerous arguments on varying forums about the syn vs. conv oils. SO if the manufacturer suggests conventional now... Why spend more on synthetic oil? Why is it conventional now?

We also have the Unlimited Mileage/Time Warranty.

Re: Wk2 hemi oil change

Full synthetic is always better than mineral. The molecules in the synthetic oils flow more freely at low temperatures and don't break down at high temperatures as opposed to mineral. That's why their grading is different too, they can be specified one or two grades lighter, which cause less friction inside the engine and therefore save fuel. Because the molecules don't break down like in the mineral oils, that's why they specify longer oil change intervals, but I replace them at every 6K.

I know that a lot has been written about the superiority of synthetic oil. I'm not in a position to dispute it.

But, if the car manufacturers specify dino oil, that's what I use. My MDX said that you may use synthetic, but that using it should not extend the change interval.

I know it is sometimes an emotional subject with most, not all, basing their decision on what they read and sometimes perceived benefits.

Here is my 'guess'. When synthetics first came out they were a good idea, and they have continued to improve. At the same time, oil refining and additives, plus engine manufacturing has improved. At this point in time, conventional oil provides 100% of the protection and lubrication that an engine can benefit from. So while synthetic may look better on paper (and in all the ads) it is over kill.

Remember two things ...

1- I said this was my guess
2- Many people swear their low compression engines run so much better on premium fuel.

Use what makes you feel good. Your car won't care.

Yep. It costs less, they recommend it and our warranty is unlimited. Saving money will win this decision. The manual says 6 months /5k not to exceeed 8k at anytime. That's pretty good for the terrible conventional oil.

And seeing as I just spent $5.00 per spark plug for these NGK's instead of the $1.99 my Champions for the 06 Hemi ill pocket the oil savings.

Why not? The only way to know if your engine oil is due for a change is to have an oil analysis done. Some engines are harder on oil than others, same goes with driving style.

Re: Wk2 hemi oil change

Is there a list of chrysler compliant oils I can take a look at? I've got some free oil changes left on my freebie contract and when it's done I will be doing my own oil changes.

Re: Wk2 hemi oil change

My owners manual says "NEVER USE STRAIGHT MINERAL OUL OR NON DETERGENT OIL AS IT CAN DAMAGE THE ENGINE" So, thoughts on the Royal Purple 5w20?? Ive been using it in 5-30 for years in my gm cars, and even in my old 4.slow 2001 jgc "upwards of 22mpg with it"



Oh ya, first post..

RP was the best 5w-20 oil I ever used in my HEMI. Longer MDS time, but more importantly, could never notice the "HEMI tick". Now running Mobil 1 but the HEMI tick is noticeable until the engine warms up.

Well, they mean what they say. Don't use "Straight 20 weight" or "Straight 10 weight" etc. The spec calls for a multi-weight, like 5w20. They are not specifying that you use a synthetic. Nothing wrong with doing so if it makes you happy. But don't use it because you misunderstood the owners manual.

I'm guessing (somebody correct me if I'm wrong) they say straight mineral oil because all synthetic sold over the counter is multi-weight.
