It's impossible to tell you which is the best motor oil without knowing where you use your car. Outside ambient temperature is very important when deciding which type and weight motor oil to use.

5-30, 10-30... I think Volvo RWD owners should be a lot more concerned about their trannies than the motors. The B230 is usually the last thing to go on a Volvo unless it overheats--so make sure the cooling system is in good shape.

Simple answer: Royal Purple synthetic. I had been running Mobil 1 synthetic in my Honda and decided to try the Royal Purple after a long talk with their rep at the auto show. My mileage immediately increased 1-2 mpg with no other changes to anything; same timing, same spark plugs, same everything. And..it's made right here in Texas.

The downside? It's expensive, about 8 or nine bucks a quart. I only use it in cars that don't leak or otherwise use oil. I also use their tranny fluid in all my cars - about 13 bucks a quart, but well worth it.

Generally speaking, synthetics are better than dino oil, no matter the brand, but I'm sold on the Royal Purple.

As to viscosity, Volvo recommends 10w30 or 15w40 (severe service).

Would pizza delivery count as severe service? It does get pretty hot and pretty cold here in the foot hills of the Appalachian

+ on the R.P.

I used the purple monster in my rotary engine, as well as their ATF on my 850R. Love that stuff !

But, on all my "less babied" vehicles, I go with Castrol.

You'll get as many different answers as replies.

Use a good quality filter, and whatever oil is on sale. Change your oil regularly. You'll be just fine.

I've been using Walmart's full synthetic because of the decent price, and 5w-30 in the winter because it gets below freezing here. And MANN (oem) oil filters.

Please don't think I'm being disrespectful, but...

Every now and then I hear claims like this, but I'm always a little skeptical. Couple months ago a counter guy in Advance Auto claimed that he immediately picked up 15hp in his "built" GTO, just by putting RP Synthetic in it. I wasn't going to argue with him about it, but if that was true EVERY single race car in the world would be running nothing but RP Synthetic.

Don't get me wrong, I like RP - and I like the fact that I can generally get it for about $9 per quart at O'Reilly's, which is not much different than other synthetics. But I guess I'm just a skeptic.
