This brings me to my question. A friend just wrecked his Civic and he made me a really good offer on his d15b7 that doesn't burn any oil and even sounds better than mine (~ 120k miles).
I've read countless opinions on fully synth oil so my head is spinning right now. I want to know your opininon as experimented Civic drivers. Is it worth to use fully synth oil in this engine? This friend that will give me the engine has never used such oil, pretty sure he always buys the cheapest one he can find.
