I know the 5w-20 recommended, but it is ok to use 5w-30 since it is more common? My car is around 100k miles. thx.

 

Gas mileage will drop a touch, but it'll work ok. I wouldn't use it if you are drive a lot in freezing temps, though.

5w30 will be better if you run higher RPMs than stock (like with a Hondata flash). This is the only time 5w30 would be my first choice--otherwise stick with 5w20.

 

I use 5w30. Gas mileage did drop a bit, but it doesn't burn off near as much as the 5w20. I only have to add a bit every 1500 miles or so with the 5w30.

 

hmmm...... i think i put 10w-30 in my dc5 last time what do you guys think about that?

 

Go for the 5 30 for the extra heat and high RPM protection.

 

Thanks for the suggestions guys. I will put 5w30 this time and see what the difference is on my car. The reason is my car has 100k miles. If the MPG drops noticeably I will put back 5w20 next oil change.

Only in a race situation (or HPDE) or if you have extended RPMs over OEM revlimit.

Otherwise Honda would not call for 5w20 if it did not protect the motor correctly. Remember--these motors were designed for 5w20. There is no reason to deviate from this unless you really, really are doing something specific that needs it.

To the OP: Just because the majority says one thing does not mean that answer is correct for everyone.

 

rsxs are known to burn oil... i use 5w 30 to fix that problem

The RSX Type S is (sometimes) known to burn oil. Also, it specifically calls for 5w30.

 

In the final analysis: YES, it is okay to use 5W30.

 

In the end.. it is ok. But I stick to 5w20 cuz thats recommended. My Wifes civic recommends 5w30 and I stick to that with it.

Yes it is ok, but it is not necessarily better. It would work with 5w50 too, but do you really want to do that?

Alot of honda dealerships have started to use 5W-30 in the EP3's that still come in instead of the recommended 5W-20 because the thinner oil is believed to be a potential cause of the pitting of the camshafts that many members have had happen to them myself included.

I rarely deviate from Honda's recommendations, but this (the 5w-20/5w-30 issue) is the exception that makes the rule. I, too, run a 5w-30 weight oil in my EP3s. Have done it for years, since they were new. Like many others, I know that Honda began recommending 5w-20 weight oil for most of its cars beginning in 2002 in order to improve its overall "fleet average" miles-per-gallon. (It's not much of a savings -- less than a mile-per-gallon per car -- but the numbers add up.) And, for the vast majority of Honda owners, there's nothing wrong with that. However, I also noticed that Honda never changed its recommendation WRT the fleet vehicles likely to see more demanding service & higher RPMs -- Type S Acuras, S2000s, etc. That seemed like an excellent reason to stick with 5w-30.

Re the camshaft pitting issue mentioned above, I think that was a metallurgical issue isolated to relatively few engines, not a lubrication issue, but it was enough of a problem for a while that it just didn't make sense not to use a 5w-30 for the additional shear protection inherent in the heavier weight oil.

 

moms car isnt honda i was reading in her car manuel that its ok 2 run a heavier weight oil in the winter because of the cold but in summer u should stick 2 recommended oil if its 5w20 use that in the summer n in the winter u can change to 5w30

You have that completely the opposite of what is true.

Thinner = winter
Thicker = summer
