Hi guys, new to the forum. I own a 2013 genesis coupe 3.8 V6 rspec manual transmission. I did the first oil change at 3500 miles by the dealer and they put in Mobil 1 5w-30 full syntectic. Im currently at 7200 miles and looking to do the second change myself. 1. What kind of vehicle you have 2013 Hyundai Genesis Coupe 3.8 V6 R-spec M/T 2. What your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4, etc.) and change intervals as well 5w30 synthetic, API service SM, ILSAC GF-4, ACEA A5 or above*3 3. Where you live Miami, Florida. Wheter is mostly hot with temperatures around 90 deg, and winters it gets down to about 40 deg. 4. How you drive (easy? hard? fast? slow?) Short trips, under 10 miles to work everyday. sometimes pulling a liitle hard. 5. What your daily drive is like (short trips? long trips? city? highway?) short trips mostly. ocasional 30 miles + trips. 6. Whether your car has any known problems no problems. car is only 8 months old. I have an SRI intake, magnaflow exhaust, getting a tune next week hopefully and an overbored throttle body and getting pulleys in two weeks. I was looking at Amsoil 5w-30 but i would like to get some feedback from you guys. Any help is greatly appreciated.
