what oil to use

[91ex4dr]

what would be the best oil for a 250,xxx 91 ex

[91AccordLX]

10w-40 or 10w-30

[ACCORDianate]

I run 5w30 in mine at 175k. She purrs like a kitten.

[91AccordLX]

its probbaly better to run a bit thicker oil because of the larger clearance with an older engine....but 5w-30 will work fine, considering its what honda recommends for cb7's.....

[LX Rida]

i use castrol 10w30 nonsynthetic

[dwf137]

10w30 for an older engine, 5w30 if it gets really cold in the winter where you live

[stroiker]

i use 5w-30 and has worked fine on both my motors, shouldnt hurt anything

[dwf137]

5w-30 is what's reccomended.. if you've got an old engine, use 10w-30..

if it's really cold outside and your using 10w-30, use 5w-30 untill it warms up..

[FishyMan]

castrol 10w-30 for mines w/ amsoil oil filter ...

[squig808]

Why would you want a thicker oil for a cold engine?

He said "old" hehe...

[FishyMan]

i've been using 10w-30 all my car's life... since we bought her, it has 81k now, do u think it'd be wise or better to use 5w-30.or should i stick w/ 10w-30 i mean could it hurt?? its summer time...

thanks..

[wed3k]

yea, i use 10W-30 also.

[FishyMan]

haha should i try 5w/=30 just one time then?? just saying...

i know a 10 plus year old car is old in its way.. but just saying... i want the best efficieny that's all..

[Mista Juice]

dude.. dont worry so much..

If you care about mileage stick with the stock 5-30... non synth... probably a high mileage formulation would work the best...

But you could always mix in some 5w40 if you are having blowby or small leakage problems... but it will affect your mileage slightly...

On a side note: I have been getting way better gas mileage since I switched from regular dino oil to Castrol Synthetic blend 5w30...
