ok so heres the scoop. i went out and bought some Valvoline 5w30 durablend synthetic blend oil for my car(2001 integra GSR) along with a fram filter. now, this is the first time i changed my oil ( on this car, i have changed oil on others before), since i just got the car 3 months ago. well, everything went fine with the whole oil change, but when i loaded the new oil in i was wowed by how clear the oil looked (you almost cant see it on the dipstick untill you get it just right on the light). well, after all taht, i start my car and take it home ( iwas at a buddies house) and i was like, OH SHIT, my oil cap is off. so i pulled over, and poped my hood. everything looked A ok. so i continued driving home, and i noticed that i could hear the motor much louder 1-4K rpms range (like, alomst a raspy, old engine sounding car). so i took it home (3 miles) and looked at my engine again, and i noticed at idle, it sounds like a really really quited diesel motor. im pretty pissed about it, but im not sure whats the problem.

I have a feeling the oil is complete shit and i need to change it, which is waht ima do reguardless, but i dunno, has this ever happened to you guys? i mean, its noticalby louder. a couple people have heard it and said it sounds fine, but i drive my car daily, and i know exaclty how it should sound.

so if you guys have any info, let me know
and oh yeah, if my engine is fucked up, valvoline is gonna hear about me for a WHILE.
