I have a 2006 Mitsubishi Endeavor with 187k miles. It is fwd with the 3.8L V6. Recommended viscosity is 5w-20. The last oil change I used pennzoil platinum 0w-20 for the winter and 10 min short trips. However, it has leaked/burned a quart in 5k miles. Also, it is pretty noisy. Should I step up to PP 5w-30 or 0w-40?

Your noise could very well be a collapsing timing belt tensioner. Especially cold starting. They collapse while sitting not running. Very common on that engine especially with higher mileage. And I'm betting the valve covers are your leak. Probably oil in the spark plug tubes as well. Those valve cover gaskets get so hard I've had to burn them out with a torch when replacing them.

Oh and 0W-20 is fine for your application.

No. Give it time. What oil did you use previously? Switching brands sometimes causes consumption. You can use 0w20 year around. Id wait til the end of a 2nd or 3rd oil change before passing judgment. I personally prefer M1 0w20 AFE or PUP 0w20. Not to say anything wrong with PP. You are basing your move to thicker oil on your perceived notion of how your car sounds and that it has consumed a quart.

PP 0w20 was junk in our Subaru - burned a ton and was noisy. It just a synthesized paraffin not a PAO or POA.

My experience with Mitsu v6 is to use a 5w30 augmented with a qt or 10w40. That was the 3 litre in my Dodge R/t. I would mechanically knock with an ILSAC 5w30 alone. Smooth as "insert simile" with the mixture. Back then I was mixing Mobil Clean 5000 "dino" to good effect.

Thanks for the responses. I will try PP HM 0W-20 next change and see if that helps.

ARCOgraphite, PP is not a paraffin, it is a synthesized hydrocarbon, just like PAOs are synthesized hydrocarbons.

0W20 IdeMitsu oil! Has a lot of moly & boron. What does the OM state about heavier oils?

I'm using Redline oil in my Montero for the first time ever. Engine is smooth and quiet, but purely anecdotal of course.

I would get that noise checked out. Going to a heavier oil is not a cure. As for oil, I might look at Valvoline Maxlife Synblend or Synthetic depending on your usage or equivalent oil.


Cannot see signatures any longer so it doesn’t matter.

Some brand new cars use more than 1qt over 5000 miles. I wouldn't be so worried.

Anyway, sometimes the PCV valve and hoses fail, and it leads to excessive oil consumption. You should really get the PCV valve from the dealer. Don't rely on the test where you shake the old PCV valve and hear if it clicks. The spring may get weak and that would cause the excess oil consumption.

We run them on 5W-30 A3/B4 here, MNZ's recommendation, but the oil sites here say the same. Mitsubishi themselves don't really care and recommend a wide range of oils. By the time they were making the 3.8 Mitsubishi had this engine pretty sorted, and they had few problems. I have seen a faulty auto cambelt tensioner, but it was after market, OE don't give any problems.

Pffft. I'm a tech at a Kia/Mitsubishi dealership. I beg to differ.
