Not concerned though I do prefer 5w30.

Shame on you KC! If you leave that 5W20 in there much longer your engine will throw a rod, fall out, or remove itself in the middle of the night and find a new home.

Haha it is full syn PP or else I probably would dump it. Getting close anyway just a few weeks now should do it.

My Nissan says I can use 0w-20. It also says that 5w-30 is perfectly satisfactory to fulfull all warranty requirements. My UOA on factory fill says that whatever the factory put in there, sure sucked. Or the engines are hard on oil. So I'll experiment with the higher end of the allowed scale, might even exceed it just for a test, and might cure the entire problem by using something 0w-30'ish. Or 0w-40'ish even. I figure the UOAs become my defense against a warranty claim if someone gets their nose out of joint about a single "not on the recommended list" oil change.

I have used 5W-30 motor oil in my Elantra, which has 5W-20 on the oil cap; however, my manual says that 5W-20 is recommended, but 5W-30 can be used as well (and also 10W-30 for temperatures > 0 deg F).


Same thing in my elantra, in fact the owners manual states you many need a heavier oil in hot weather.
I run 0w or 5w 20 in the winter and 5w 30 summer.


I don't understand why you, and others like you, just don't use the same weight oil during all seasons. I am not dogging you, or trying to be sarcastic, or even trying to ruffle your feathers. I mean, the oils you stated in the sentence I quoted, are so similar to each other that you can just pick one and use it all year round.
Ah well, if you sleep better at night doing it your way then go for it!

I am guilty of something similar; I always use a new oil filter at every OCI and some members dog me for that; the ones that think that at each OCI, instead of throwing the used oil filter away, use it again. And, my answer to that is, "One Filter, One OCI!"

The chart in my Elantra owner's manual shows that both 5W-20 and 5W-30 can be used for the exact same temperature range (the same on the cold side and hot side); thus, either 5W-20 or 5W-30 can be used year round in my car. The only viscosity that shows a different temperature range is 10W-30, which can be used for temperatures 0 deg and above. Therefore, from now on, I will only be buying 5W-20 motor oil for this car. There's really no reason for me to use different viscosities for the winter and summer.

I'm the same way ... I always use a new oil filter when I change the oil. Just my preference.

Agreed, but since there is very little start up advantage to a 5w20 over 5w30 in the coldest weather, why not use a 5w30 year round? That is ultimately my plan.

You're right ... either one can be used year round. I guess it comes down to which one you prefer ... and maybe 5W-30 would be the better choice?

I agree. Why go on the cheap with expensives engines. Not sure what the logic is with mixing more old oil than you have to with new clean oil, with the small price of an oil filter.

I think so but ultimately I realize I am splitting gnat hairs, but that is what BITOG'ers do best!

My next OCI will be 5W30, I think.

I'm tired of all this light weight oil talk! I'm going back to what I ran in my 1985 Honda Civic Castrol GTX 20w50 ...lol

That's nothing! If I can find some Kendall GT-1 Nitro 70, I will run that! I used to use it in some of my race engines back in the late 80's.

 

[Merkava_4]

At 105*F outside today, the 10W-30 was dripping off the dipstick with the engine COLD.

I don't like seeing oil run off the dipstick.

 

[Garak]

Then move here and use 20w-50 all year, Merk, see how much dripping it does.

 

[Scum_Frog]

To the OP, I have run 5W30 in a vehicle spec'd for 5W20 the odd time.

1) The vehicle was out of warranty
2) This particular engine was spec'd for 5W30 for years and then they changed it to 5W20.

Wouldn't the "drippy" oil be quicker at lubricating than thicker oil?

Typical muck post.

Try a straight 60 grade then.

You are aware that an engine at operating temp has oil that's much thinner and "drippy" right.
Because cold oil is far from optimal.
Drip,drip,drip

Just a correction on my post: My plan was not to buy anymore 5W-30 oil for my car; however, I still have 5W-30 oil in stash that I will be using. Actually I made an error on my most recent oil change post because I got ahead of myself that day and made the post right before I did the oil change .... I posted QSGB because I had planned on using some of the QSGB 5W-20 I had in stash but then remembered I still had 5W-30 oil in stash, particularly Formula Shell 5W-30 with an older date on it as well. Thus, I decided to use it instead, and I just got around to making the correction to the oil change post today.

Anyway, all that detail/information wasn't really necessary .... but, the main thing I wanted to mention is that after reading your post and thinking about it again, I haven't totally ruled out buying 5W-30 motor oil for this car in the future. Also, the Formula Shell 5W-30 is running very nicely in my car, and what makes it even better is that I remember buying that oil at a very good, low price ... and I might get some more of it in the future. I can't really go wrong either way I guess, so I guess it doesn't really matter. Whatever I decide, once my oil stash gets close to being used up, I will probably end up choosing to stay with one from there on out (either 5W-20 or 5W-30 from that point on) without looking back.

After i use up the stash of 5w20 pen ultra, i will run 5w30 all year.
