This entire thread is hilarious. Go with the manufacturer's recommendations... Funny how people are influenced by brands for oil...plugs....filters...intervals. These companies are playing you by influencing your thoughts on basic maintenance items - just because this is all that you can do personally to upkeep your vehicle. Oil is freaking oil...and filters match OEM or they do not. That said - please continue to pay more for different brands - and trust me, that quality of oil will make your air conditioner work well for that much longer

. Who on here has had a stuck valve or needed a ring job recently?
