What type oil should I use???????????????

[CivicSier]

I currently have 1 day on honda oem filter with castrol GTX regular oil.
I think the previous owner had synthetic, because after changing the oil it sounded a bit louder.
Could this be all in my head? Would it be alright to switch dino to synthetic and vise versa?
What type(syn or dino) and weight would you recommend, also what brand?
What happens when synthetic mixes with regular oil if this occurred in my engine?

And what should i use valvoline, castrol, or pennzoil

change out to a synthetic 5w30 like royal purple or amsoil

Synthetic 5w30 or 10w30 in a stock k20a3. Just stay away from 5w20 to be on the safe side.

Take a peek in the oil section. ill moved the thread over there for you.

Shit I used 5w-20 would that cause engine noise?

I don't know for sure but I just know most people on this forum recommend against using it because of potential issues with the cam lobes galling. Apparently the oil wasn't the whole cause but issues with the actual metal itself. Either way, most people here advise against it. I'd just drain it and put in 5w30 or 10w30, the filter itself is fine, just take it off and drain it, just let as much drain out as possible from the pan.

Is this for the smashed up ep you're fixing?

Valvoline, Castrol or pennzoil ?

I've been using Mobil1 but there doesn't seem to be much love for that around these parts. I've only done two changes since I got the car and I'll be switching to something else. Lots of love for Amsoil, Royal Purple, Castrol Syntec from what I've read.

I used to run Royal Purple, but I hated it...now I'm on Motul and thats it. Haven't used anything else for the past year and a half.

[talonXracer]

The Pennzoil Platinum would be my selection of your 3 choices

[TheKone]

Amsoil 0w-30 here. Absolutely love it. Motul is good too. I've heard some sketchy things about royal purple like that it is thinner than advertised which helps there horsepower claims but sacrifices engine protection. Just word of mouth though.

[CivicSier]

The Pennzoil Platinum would be my selection of your 3 choices

I talked to a machanic and he said that is was good stuf. Would you recommend the ultra or platinum?
Would I have to change the filter to? Or would a dain of the filter be ok? If I have to change it is there a non honda filter that meets or exceeds? The dealership is kind of far from me.

[CivicSier]

What about Valvoline SynPower synthetic, Any good?

[RedSiBaron]

Honestly its a strong name brand, it'll all work...until you get into the expensive high performance oils there wont be much of a difference

If you go with say royal purple you'll notice hp and mpg increase, but you'll prolly need to add a qt per 3k miles or less...

Amsoil, redline, motul will do the same thing but they can handle heat a lot better and you wont burn nearly as much...
