Im new on here but not new to forums at all. I did some searching on here and other threads on the net. I have a 2000 Honda ex with the 1.6 vtec manual trans. My question is I bought this car from a guy who has worked as a tech for Honda for 15 years. He bought it off a customer who ran it dry on oil. Before that it always had synthetic and after a complete rebuild of everything it now has 45k on it. He swears by Valvoline synthetic even over Hondas stuff. Can I get away with going to a conventional? I don't mind staying synthetic because I do like the 7000 mile change intervals. I drive a lot of highway. I drive pretty aggressive mainly on curvy roads. No im not 16 I just like how the car handles...lol. I do run 5w30 like the owners manual says. I have read I can do 5w20 as well but it gets quite cold and quite hot here in Missouri. 106 today. Id like to go back to Mobil 1 that ive always used or ive had good luck out of Castrol gtx for a conventional. Sorry for such a long post my heads spinning from all that ive read over the last couple days.
