Better to use 5W30 synthetic because the lighter oil is drawn up into your engine when it's not running. In other words, you don't get the wear on engine start. You also get more power to the wheels and better gas miliage, I would guess 1.5 mpg.ating Newest Oldest. Best Answer: 20w50 will increase your oil pressure, since it is thicker oil. I wouldn't suggest using it in your honda since they generally take 5w30 which is way thinner. That thick oil may not drain into the oil pan fast enough. Especially since it sounds like you are turning some high RPM's.
