hey guys is all synthetic 5w30 oil the same or different? cuz im using mobil 1 righ now and everytime i do an oil change i have to buy a filter from honda and like 5 quarts of mobil 1 and bring to my mechanic to change, and it costs alot, theres a oil change place just opened near where i live and they use castrol synthetic, and it mite be cheaper if i go there to do it instead, so is it ok if i switch from mobil 1 to castrol?

 

Do it yourself! Stick with the Mobil1-- Castrol blowz

 

I agree do it yourself it doesn't take much...

Mobil is the best...the one in the silver container 10-30
