What oil do you use for your initial start up on a new motor?

I have been told to use a non detergent 30 weight such as Valvoline 265 for the initial trailer or dyno run for the first ½ hour under light load. This supposedly helps with ring seating. Then change to a heavier race oil for initial, loaded break in on the water or dyno.

After break in change it again to your favorite synthetic such as Amsoil 20-50 Racing.

What’s your preferences?

Dave

The cheapest 10w30 you can find. Run it a 1/2 hr, drain it, more cheap stuff, 1/2 hr drain it and change filter, then put in the good stuff

Straight 30 WT. Low detergent allow for better breakin. If this is a hyd. roller or mech. roller. After breakin you can go to synthetic. If flat tappet. Need to run a quality Petrolium based oil on the dyno and in the boat for about 25 to 50 hours. Then go to synthetic.

Maybe I should have made this a poll

It at least seems to be a unanimous choice to use non-detergent for initial running

Lycoming recomends .... ok guys... hold onto your hats... 100 w non detergent oil for the first 25 hours of use.... I don't think I want to be flying in an airplane with 100 w oil trying to circulate in the engine..but that is what my pilot buddy says they recomend for break-in. Scary....
