Winter runs almost always bring worse numbers. Silicon and Aluminum are high for the miles.

Silicon is actually trending down. It was 22 on the last uoa. I agree that the aluminum is high. Why use Tufoil? Tufoil makes the car run so much smoother and I have talked to a lot of mechanics that love this product and I have been using it for the last 3 uoa's. It doesnt seem to harm anything so I keep on using it.

Nice run! Good choice on the OF and AF. I'd drop the Tufoil but that's just me.

Thanks, its a better choice since I paid $14 for the PP and $1.50 for the Fram XG filter. Sometimes its pays off to work for Wal-mart. :)
