Thank's John ,I checked it after putting a good weekend of driving on it and it seem's a.o.k.Not to plug anything but a friend turned me on to being a prefered customer to amsoil.It is the only oil that i have found that let's you go 25,ooo mile's between oil changes.Everything i own with a motor has synthetic.About 12,5oo i put on a new filter and a fresh quart of oil.So far with the cold weather in IOWA it saves on the batteries and starters.With the synthetic blend i used in the old truck it sure seem's to purr right down the road.Have a good summer and thank's again,Chad.
