If you want to put the best oil and best filter go Mobil 1 full synthetic. This iin my opinion and a lot of other peoples if the BEST oil to use. I've never heard of Kendall and i'm sure its just some off brand cheap oil. Also if I were you I would get some Rhino Ramps they sell them at most auto stores and change it yourself. I have heard some horror stories about people not putting the drain plug back in and well you get the picture. Plus there is a certain satisfaction and Zen about Changing your own oil and it only takes about a half an hour. Jus my $0.02.
