I would go to IPD and buy a tune up kit. It comes with cap, rotor and plugs.
IPD offers several differnt brand of plugs and they can advise you what might be best. I just checked online and they are currently having a sale on their tune up kits.

15/40 Rotella is not a bad idea either.

Reach IPD at http://www.ipdusa.com

Good luck.

Helper,
Go easy on the terminology. I think you know what he is asking.

Baneps,

I would suggest the the Volvo three prong and you might give Rotella T 15W/40 a try. Real good non synthetic oil with a nice additives package to really bring it up to the top of the heap in dino oils.

Stay simple and go with what the manufacturer recommends. FR7DC plugs and Synthetic 10w-30 is sufficient.
