Synthetic or a mineral oil?

[Tomas]

Hello everyone

Im gonna make my first oil change this weekend. The owner before me have used fully synthetic oil 15W50. Shall I go for the same oil again or can I go for the same oil that I use in my Corvette. There I use Valvoline Racing 20W50 mineral oil.

And what about the transmission and the rear axle, what do you recommend me?

regards


Tomas

Use Synthetic , but Mobil 1 10-30w is fine, and even recommended. Call our service dept. for the correct tranny and rear diff.fluid and modifiers , as it is year dependent.

Ask for Nancy Shanno or Mark Jorgensen

STAY WITH SYNTHETIC.
Supposedly you can switch from mineral to synthetic (may STOP oil consumption- bigger molecules), but NOT from synthetic to mineral. It can cause oil consumption.

Tranny - you can use Dextron III Castrol Syntorque LT (Mopar #4874459)

Diff - Mopar High Performance Synthetic Axle Lube
SAE 75 W/140 (MS-8985)(Mopar #4874469)
Mopar Gear Additive (Mopar #4318060AB)

You can also go with Redline brand of synthetic for the above as many have had good results with this brand of synthetic lubricants and oil.

Why bother, isn't it snowing there yet?

 

[Tomas]

No snowing here yet, we have still here about 20 degrees celcius some days, but the summer is over. Maybe 2 months before it will start snowing here

Okay, skip my post, as I read it quickly and saw the Hawaii reference - duh. I agree, call JP da Swede, und yous will get gouda advice, Ja schure. The only Viper in Finland and that has to be a major chick magnet!

Tomas:

Do not use the Dexron fluid, the upgrade is the 75/140 synthetic. It is a huge improvement over the Dexron, it pours like 10 weight and is 145 weight under load. It also eliminates the majority of neutral gear rattle.

I think Jack B meant that he recommends Castrol Syntorq 75W/85(MOPAR calls it Synthetic Manual Trans Lubricant 75W/85)for the tranny over Dexton...please note that the recommended synthetic tranny fluids are 75W/85 and NOT "75W/140" which describes the lube for the diff...a "minor" point til one uses the wrong fluid !!!

 

[Jack B]

You are right, my error

Hello

No one using Valvoline oiles here? Just Mobil 1 or Castrol?
