Mobil 1 oil weight
Today I was at Wal-Mart and was going to pick up some Mobil 1 full synthetic oil.
Last season I was using Mercruiser 25W-40 semi-syn oil and then when I winterized the boat I changed the oil and used Rotella 15W-40.
I figured I may as well switch over to full syn oil now.... I couldn't find the Mobil 1 in a 15W-40 or anything close to that. The closest I found was 10W-40 & they also had 10W-30 & 5W-30. I know I need a little heavier oil.
I also noticed they make a high mileage and extended performance oil, but again I couldn't find the right weight.
I was just wondering what weight you guys are using?
I tried searching, but it doesn't seem to work so good.

The '98 has a recommendation of 5W-30.

I run the extended performance 10w-30 in my 02 LSV. Have not had any issues yet and run this in my 08 tahoe. My dad just sold his 88 Chevy Suburban with just shy of 300,000 miles on it and we NEVER had any engine issues. He ran the 10w-30 extended performance and it was running great when we sold it, just wish the rest of the truck was in as top shape as the engine!!!

I think they hit on all the pros and cons. You can decide for yourself. For the record, I fall in the conventional but change it very often camp.

I'm currently using Mobil 1 5w-30 synthetic in my boat. The Mobil rep for my area uses the 5w-40 synthetic in his boat.
