General service stuff

[Viper Craig]

Hello there,

Just a couple of questions about servicing. What kind of sparkplugs are needed, will regular do or should they be platinum? Also i've seen the subject raised about 10W 30 grade oil, i've got 10W 40 grade, will this make any difference?

Thanks for the help guys and girls!

Regards,

Craig.

Hi Craig,

The stock plugs work just fine on a stock motor, Champion RC12LYC gap .035". You all can't get Mobil 1 10W-30? Mobil 1 10W-40 will work, just give her a little more warm up time before going out to play.

Hi was poking around this forum as we are planning on buying a Viper in a month or so. Concerning the motor oil, the difference in 10/30 and 10/40 shouldn't be seen on start-up as the lower numbers, which represent cold temp protection, are the same. The 10/40 should have slightly higher viscosity number etc when hot. The move to lower vis numbers was initially prompted by auto manufacturers seeking a quick fix for better mileage to enhance their CAFE.

Chuck,
Thanks for the well wishes. We hope to be in one sometime in June. First order of business is selling the Esprit.

My explanation was a little cryptic on the multi-weight oil. While the 10/40 is a "heavier" oil. The viscosity when cold should be the same as the 10/30. When hot both are thinner but the 10/40 shouldn't be as thin as the 10/30. If I remember correctly, the additive package is the key determining factor. I'm five years removed now from my days with the oil company.
Thanks again,
Bill
