Is there anything special I need to do to change to syn oil? Just drain the pan change the filter and put it in?
-
If you go to syn oil and have the slightest leak, it wont be a small leak anymore. Pros and cons on syn oil. I found out the hard way. but ya as far as i know just change your oil. The filter should be change before your next oil change, syn last longer than conventional oils. i change the filter between oil changes. i run full syn in my yota ;D

Is this for car or boat? If it's a boat I would run the 15W-50, since marine engines are pretty much under a heavy load all the time. I've been using synthetic in some of my cars (Toyota Tundra and Jeep Wrangler) and my jet boat for more than 10 years. In a couple of old cars I have, 68 Malibu and 69 Mustang, the synthetic doesn't work as well but those engines are old school builds and I can hear the lifters clatter a little with the synthetic so they get dino oil (if I ever build them again the engines will be run on synthetic). I've had the Chevy SBC in my boat apart a couple times and having run the synthetic it's very clean inside, no gunk anywhere. I use Mobil 1, because it's been around a long time and also it's readily available at a reasonable price, but I'm sure others will chime in with their favorite.

Moblie-1 is my choice to ;D

At least 20 hours on the new pistons/rings/bearings. These were put in after about 30 hrs on the fresh rebuild. I replaced hypereutetic with forged pistons. I put in the Mobile 1 10W30 after talking with Jet boat performance. They said 20-50 was what they use, but the 10-30 should be fine. I will replace it with a heavier blend if I sense any problems. I can't imagine it will be anything but better than the 10-30 regular oil I was running in it... :-\

On both of my cars and my boat, every time I run synthetic they burn a quart. I go back to regular oil and its fine. Doesnt burn any. I run 10w50 in my boat (BBC) and no leaks/no burn. Just my $.02
