So I'm at about 83k miles on my car, and the burning oil issue has been pissing me off lately.

FYI, i'm using castrol gtx non-syn 10w-30 and OEM (older style big) oil filters. If i'm aggressive, i'll burn a quart every 1000. If i take it easy, but not grandma, I'll get 1500-1800 miles to burn a quart.

I was told from a Honda-Tech member that going to 15w-30 will slow the burning. He was having the same issues with his high mileage LS-Vtec block, and once he did the switch it didnt burn nearly as much.

So my question is: Is it bad for the oil pump or anything related to go up in the weight of the oil? Because I'm due for an oil change in about 400 miles, and I was seriously considering going to 15w30.

I know of a number of instances where friends with higher mileage cars up the weight of their oil because of their mileage. I even have a friend with a 90-93 accord with like 150k and he's using 20w30 or something crazy like that.
