Best Oil Viscosity for B18A?

I have a 1991 B18a1, and the previous owner ran 20W50 Castrol Syntec Synthetic Blend. Everybody told me it was way too heavy, So then I started running 10W30 Castrol Syntec Full Synthetic oil. It ran nice but it burns it up quicker and I was wondering if I should move up to like 20W40 or something around there. I recently heard people use heavier oils in B series motors that rev high. What should I use? The motor has 114,000 on it





it tends to burn up when i drive at a constant rate of 120 or more for an extended period of time





I think I'm going to stay with castrol syntec, its the best oil i've ever used so far. The car drives really well with it. I'm just questioning the type of viscosities and what I should use. I think 20w50 was too heavy, but for a B series, 10w30 is too light, burns up to quickly

whoa, first off all your car shouldnt burn oil at all.


Ive heard of people using heavier weight oil like 20w50 when a car burns oil or has alot of mileage.





but 5-30 is best but with some miles like yours 10-30 is perfect.


not too light or too heavy. have your car checked for compression, your car should burn oil, hondas are notorious for piston rings going out.Best Oil Viscosity for B18A?
Most people are familiar with oil's viscosity ratings. The ';W'; refers to ';winter,'; not ';weight.'; For a B18a1 engine an oil with a viscosity of 5W-30 is preferred for improved fuel economy and year round maintenance and protection. You may use a 10-W-30 viscosity if your are living in a place where the temperature ranges from -5 to 45 degree centigrades
