all the way. MT too.

 

Castrol GTX High Mileage 10w30

 

why??? I was thinking about changing to synthetic... I have a d16y7 too..

 

synthetic is just plain good, everyone has opinions, like seals start leaking, if they do replace them. a rubber is cheaper than a berring to do

 

Synthetic blend from Canadian Tire. I used it before in my '91 civic before selling it for a '95 Odyssey with good results.

 

RedLine Oils 5w30 Synthetic - B16A2.

 

the blend i never understood the theroy behind that except price? am i far off?

 

some1 answer this ?....

 

Synthetic oils resist thermal breakdown and losing it's viscosity (how thick the oil tends to stay when heat is added). Plus sythetic oils tend to last longer and don't have to be changed as often as regular oil - so it can save you more money in the long run.

Regular conventional oil tends to break down quicker and loses it's viscosity as more heat is applied. When this happens your engine's internal metal parts can get closer and closer and make contact causing friction and wear.

 

That's a great explanation.

Q: Why is synthetic not good for high milage engines?

Also, if someone uses synthetic oil twice as long as regular oil, they should still replace their filter every 3,000. Right?
