Proper oil for turbochargers

[rwolfarth]

I'm in the process of boosting my 03 Accord. The kit is listed below, and I'd like the motor to last as long as possible: I'm adding an oil cooler after the kit is installed. I'm wondering what kind of oil is best. I talked to the owner of the shop and he suggested 15w-50, or a combination of 15w-50 and 10w-30. I'm not sure how safe it is to combine two different oils, but I know that the higher the second number, the more resistant it is to flow. Additionally, Honda suggests 5w-20. That tells me that a heavier oil won't "fill" all the hard to reach places in the motor. What do you suggest? I live in Ohio, so I'll have to deal with colder weather 4-5 months out of the year.

Thanks,

mobile one 10w-30 full synthetic. change oil every 2500-3000 miles. /conersation unless it hits negative 40 degrees f. you don't need 5w-30. but always run full synthetic. you can pick up 5 qts of mobile 1 synthetic at wallmart for 22.30

10w-30, either a high quality petroleum oil or just about any synthetic. I would probably opt for a 15w-40 petroleum or 5w-40 synthetic in the summer.
