    I run straight 30 weight in all of the mowers that are air-cooled.

    30 semi synthetic. Got a great deal on some and have had great luck with it in the past.

    Is there any advantage to running SAE30 in the air cooled engines instead of 10W-30???? We've been running 10W-30 for a while but are definitely willing to change for a good reason!
