Royal Purple Roughness?

[jtaylor]

Hi guys, i might have mentioned earlier that my engine was getting rough after only 2000 miles on Royal Purple 5w-20.
So I added 6.75oz of seafoam(rec'd amt) and it seems to have opened up the engine a little bit(seems less restricted). but now its starting to sound more like an american v8 rather than the precise v8 of the M3 that it usually sounds like. The seafoam has only been in there for 50 miles, trying to clean the engine out completely before i jump to buy redline (expensive).
Has anybody else had these problems (with royal Purple and seafoam)?

You guys are nutz watering down perfectly good oil. I would never put that in my crankcase and put a load on it.

 

[jtaylor]

it felt rough and disgsting, i heard that seafoam will clean it up a bit, Im def gonna just invest in redline soon tho. will the seaoam do damage>?

 

[d00df00d]

Just to be clear: Did you add the Seafoam to the oil, the fuel, or the intake system (by the vacuum method)?

 

[DieselTech]

what do you think it has done to your already very thin oil? IMO I wouldn't drive another mile with it in your car. MMO would have been a much better option.

 

[jtaylor]

I added it to the oil. What should I do? Just order the redline and drive really easy till it comes in?

You definitely want to drive as little and as easily as possible until you can drain the oil. The elastomers in your gaskets and seals don't like heavy solvents.

I personally would drain it and just put conventional in until the redline arrives. I wouldnt drive with that stuff in the sump

Agree with this guy

ok guys, so here's the deal, I called the nearest walmart and they are stocking pennzoil ultra for $25 for 5 quarts, which is epic pricing i think. Ive heard its a very good oil. Im gonna pick up some 5w-20 tomorrow. or should i go with 5w30, keep in mind i have cylinder deactivation on my car (maybe that means i have to go with the 20?).
Thoughts?

Use whatever the owners manual says to use.

 

[d00df00d]

Stay with 5w-20. No reason to go heavier unless you see drastically higher temps than normal.

No offense man, but why exactly would you use Seafoam on a three year old motor, let alone a Honda motor? I wouldn't use Seafoam period in any of my vehicles, although I have read about its use and know that people believe it cleans out their motor. What I don't understand though is why would you think an extremely efficient Honda motor from a 2008 model could possibly be dirty enough to use a product like Seafoam on it? What kind of mileage is on your car? Less than 50k?

As the others have said drain that stuff out immediately and use whatever oil is recommended by Honda, which I believe is a 5W20. Personally I'd just go with Motorcraft or PP. There is really no need to spend the extra for Royal Purple or Redline on an Accord motor but it's your money. If you feel like spending it go Redline and leave the Seafoam out of the equation.

1st of all you have hurt NOTHING running the Seafoam in your oil. NOTHING!!!!!! It is 100% safe to do that. It is not a harsh solvent that is going to hurt your gaskets or seals. Yes, it is a type of solvent but it is 100% petroleum based and is 100% safe for use in the crankcase. OMG some people on this site just talk without a clue. I have run Seafoam in my vehicle's crankcases for YEARS for everything from a moisture remover, to freeing stuck lifters, to a flush in dirty engines. It has hurt NOTHING!

I actually use it before every OC in my current vehicle( 2008 5.7L HEMI Ram ). Just so happens that means it is added to RP 5W-20 like you. I do it because it helps remove moisture. The PCV system design on my vehicle stinks and leads to a lot of condensation in the crankcase. Even running it to full operating temp doesn't get it all out( winter anyway ). The Seafoam helps a lot with this issue for me.

Seafoam is an excellent product as is the RP oil. neither by themseleves being added should cause your engine to run rough. Actually, RP is probably the best oil I have ever used for making engines smoother as a rule. How many miles on this vehicle? What kind of maintenance was done on it prior to this fill of RP? Are you the original owner or did you get it used? Is it possible it was not maintaned well and has a lot of miles? If so maybe the RP dissolved a lot of crud in there and has overloaded the oil filter and effected oil flow which can make it feel like the engine is running rough.

About all I can think of. Neither the RP nor Seafoam should be causing a rough condition? I would suggest changing the oil and filter right away however. Not because you have caused harm with the Seafoam or because the RP is a bad oil but because it sounds like it is needed now. Check out the oil real good for any chunks and gobs of goo and compare the weight of the filter you take off( drain what oil you can )to the new one to see if the old filter is really heavy by comparison( which means it is loaded up! ). Try the Ultra you are interested in and see how it does. Sounds like a good plan.

If things still do not smooth out I would look for issues other than oil or additives.

X2.

The oil is not likely to cause roughness.

I've seen some people screw things up by using seafoam in the intake system, but the product itself is virtually harmless used as directed.

Get the Pennzoil Ultra 5w-20 with the weight the manual says.

Your car is so new you should not need any other additives or a thicker oil.

You got that right. Seafoam & MMO in good synthetic oil is about like washing your feet with your socks on.

 

[mechtech2]

It was a bad idea to put Seafoam in the crankcase.
It is especially bad because you do not know what is causing the roughness.

Umpteen jillion things could be at fault - who says it's from the oil??

 

[DieselTech]

Get yourself some redline SL-1 and redline 5-20 if you want to make sure it's clean. Nobdoy on this forum is sitting in the drivers seat so when you say roughness nobody know what your term of roughness and what somebody elses term mean.
