I agree there. I tried using my block heater a couple times this winter. Made a definite difference in how quick the car warmed up, got defrost/heater, better gas mileage too. Nothing like starting up a car with coolant that's 50F above ambient temperature. The pre-warmed oil helps too. Alaska's "plug at 20" program has been a huge success in pollution reduction. I would imagine the benefits in engine life are a big plus as well.

I agree with Kraest on this one though. I think 5w is the way to go for most of us on the board.

 

I have tried Royal Purple, Mobil 1 , Wal Mart Super Tech, Pennzoil 10 W 30 dino, and Pennzoil Platinum ( in the car now ) . The previous owner used Castrol 5 W 30 ( I Think ) dino - I got the car w/ a tick under 24K.

All seemed to burn about the same amount - ~ 1/2 qt. per 1500 - 2000 miles, and all were changed when the oil change light came on, which is typically pre 5K.

I am at 84K now, and have never noticed a lot of gas mileage diference w/ any of the oils. My highest ever on the highway was 25 MPG, when the stall was in, but my diesel truck having gun buddy was driving for that tank.

I had a co-worker w/ a '00 SS that swore that RP gave him better mileage. Different motors in different cars, I suppose.

Save $'s, buy the Wally Worls syn, and change it every 5K or less - you'll be fine.

My preferred weight is 10W30 , BTW , but the Pennzoil Platinum is 5W30 as that is either all they make it in, or all that Pep Boys stocked.
