so i dont see why you would want to swwich to syenthetic oil so bad if the old stuff is wworking well...castrol is a good oil...id say you are better off just sticking to reg oil. you dont gain much more hp. Plus ive heard the that sythenetiic stuff will usally take off the permante coat of oil film on your enginge that you get from when you break it in.....also they do not have a oil filter that will last as long as the oil....from what i can tell. So you have to change the filter before the oil the fill it back with more so you dont save money.......its alot to worry about for the tiny bit of horse that youll never feel..................i dont do it becasue of the hasel
Motor oil does not increase HP. It is just an advertisement for the most part. If it does, it's 1-2 MAX.
Royal purple does leave a film, even though it is synthetic. Synthetic also cleans the non synthetic oils out. You'd be surprised at how synthetic can out perform non synthetic oils.
