what oil r y guys using for a stock dx? im changing my oil and im having a mental block for what to use like 10 w 30 or somehing?

[Tanked]

I'm using 10w-40 in my LX, although it's really supposed to use 5w-30.

use 5w-30 or 10w-30, but if you already got 10w-40 bought you can use that too, it wont hurt anything. Im pretty sure homda recommends 5w-30.

i use mobil1 5w30 in my rex dx,
throw a little no smoke in to deal with my burning problem and it runs nice with it, but to be honest with you, i think just keeping the oil changed regularly is a lot more important than what kind it is.

Actually, a lot of the newer engines designed run a lot smoother on 5-30 than anything else. If you have a premium 5w-30 oil, dump that in there, but I'm not too sure if our 4th gens really fall under the category of "newer cars", but thats okay. I use premium 5 30 every time in my 91 lx, and it runs like a dream.

I think if the engine is in really good condition, the lighter (5w-30) will work better...slightly better power and fuel economy because of less resistance. However, the heavier 10w-40 or 10w-30 will burn slower because it can't get past worn rings and seals.

5w-30 is preferred
I got a whole bunch of Penzoil Synthetic 5w-50 that I use now.

Its "normal" for a honda to burn/eat 1qt per 3,000 miles

It depends on where you live...5W30 has a wider range of temperatures. As in below zero to like 120F.
10W30 has a higher viscosity so its better for higher temperatures. But it kinda suckors at zero.

how well do 4th gens respond to synthetic? Jus wondering.

[blue4g2def]

well, just in general, older cars should stay away from synthetic.

Synthetic is great if you start using it right away on a new car, but if your car is old and burns any oil (leaks in piston rings, seals) itll flow right through and will end up being a waste of money.

or am i wrong? im no expert.

Newer engines will benefit more from synthetic than an older engine.

If the engine leaks bad or burns oil severely then i wouldn't bother with synthetic.

There is "high-mileage" oil that actually works.
