Ok so i did some lerking around here before i signed up and have read some pretty decent reviews on valvoline syntech and others and have heard RP isn't so great or at least as great as they make it sound. Ever since i got my car i been using different oils and i liked valvoline syntec the best. I used some quaker state and then switched to valvoline syntec. I noticed the valvoline gave me better throttle response and the engine felt rev happy. After using that for some time i today switched to RP to try it out cause i heard a lot about it. It made the car feel smoother and feels like heavier oil (throttle response didn't improve). I didnt feel that new feeling of an oil change that i got when i went to valvoline syntec. I am looking for an OTC oil that i can use for mild racing and street use and doesnt cost like this RP bullisht. Can valvoline syntec be it for me? Thats the only oil i really felt a difference with when i switched to it. Pennzoil platinum?
