show me where it says 5w-30 is "non recommended" Anyhow, notice that trend in your comment, that you always run factory recommended, yet that trend is thinner and thinner oil, its all about meeting EPA standards and thinner and thinner oil is an easy way. So you keep running factory recommended and ill gladly add some more protection for my engine at the cost of a few extra dollars a year. and Im not spreading hearsay, i've seen the water thin oil come out of the car after 7k miles. Once I saw that, It was 5w-30 and no more than 5k mile intervals.Not sure how my reading comprehension is low . Seems like everybody in this thread is concerned about how people spend their money on oil changes.
I get what you guys are saying and I understand there’s a lot of distrust for EPA ratings. However, oil has come a long way in modern times. There is literally nothing but hearsay being spread in this thread. Go to any car forum and you’ll see the same. People talk about how the manufacturers recommended oil weight isn’t the best for the engine like it’s some sort of conspiracy.
I put nothing but factory recommended oil in my cars and have never had a problem—and I race my cars (not my civic obviously). A WRX, Miata, and now my Corvette. My 2011 WRX I raced for years with the factory recommend 5w30 without issue. The bearing issue is completely overblown. The 4 cyl ringland on the EJ257 is not; one of my racing buddies went through three engines on stock and stage 1 tunes. Yes the 5w30 shears down a bit, but nobody seems to stop and think that perhaps the engineers knew it does and thus recommended 5w30 instead of 5w20 or 0w20? You bet your ass they did a zillion oil analyses when developing the engines.
But like I said, you guys are welcome to continue using the non recommended oil weights. Won’t cause any harm but you might lose a few mpg.
because he doesnt want to and knows what a high heat forced induction does to oil.....Why not 0-20 ?
