ka runs like crap after royal purple oil change.

[S13 240SX]

Hey I need some of ur guys thoughts on this... i have a stock 117k well taken care of ka24de, I always tune it up and do oil changes every 2,300 miles.. I did an oil change 2 days with royal purple and now my engines feels like its running so dry cuz when I try to step on it engine makes no power and it doesn't even feel like its a twin cam anymore.

the oil i used before the royal purple was quakerstate high mileage with the mix of slick 50.

Anybody else have bad luck with royal purple on their ka's?? I know its good oil but I just don't know if its smart idea to use on a bone stock ka with just an exhuat and intake. What ya guys think?

[adrianfromthecastle]

i used RP (<- i'm using that from now on) on my old KA.... 10w30 and it ran fine all the time. so i dunno i even use it on my sr

[S13 240SX]

i'm using 10w30 as well.

i think that using that oil on a "bone stock" engine has nothing to do with your problems. honestly, why would it? you might have broken loose some **** in the engine and it managed to work its way into a part of the engine that caused it to malfunction. my suggestion, run sea foam through your oil and replace...

[neverlift]

rp should work fine in any engine its friggin motor oil. I will say the qs you ran may be coming into play,I wont go into detail but qs sucks a$$ juice. IMHOdont know **** about that slick 50 stuff but its bs! nissan says not to use oil additives,they muck your engine. The only 2 I'd say might be ok are lucas and MMO.

[dickie]

um, oil additives may increase the amount of sludge in your engine.

maybe you drew something into the oil pickup in the pan thats clogging it?

[CleanSfourteen]

um, oil additives may increase the amount of sludge in your engine.

Bingo... Slick50 is just a scam like Prolong or Duralube, modern motor oil comes with plenty of additives and is not made to be mixed with anything else... Will clog up your engine alot better than it will help it!

If you want good oil check the back label for the API rating in the middle of circle, Royal purple is okay but i gave it up, Mobil1 is the best, end of story.

But that may be my bias, and I'm not chemist, but as long as it says API-SM grade, then it's premium motor oil to me...

Also, did you check your oil level??? it can have quite an effect on an engine, like one with too much motor oil sloshing around in the crankcase... US automakers used to rate their car's horsepower with minimal oil for better numbers, which has since been outlawed.

oil change every 2300 miles ??!!Now that is just a huge waste of money and a big source of pollutionI change my oil every 5k miles with the synthetic - and I know it could go longer...I did an oil test with blackstone a while back on my oil that had 6k miles on it -- and it came out perfect - I could have put another 5k miles on it.This is all using Mobil 1.

The important part I beleive is to make sure to drive the car around a bit before changing the oil so that it becomes a little warm and flows out much better.

[tonynalli]

mobile 1 is one of the best comericaly made/availbleproduct. But I wouldnt say its the best. There are others out there that are better, you just can't go and pick them up at your local gas station though. I dont change my oil but every 15k miles. I do however change my filter every 5k or 6k. My oil usually still looks new when I replace it too. Most people got this idea that you HAVE to change your oil every 3k miles. I think Jiffy Lube made that one up. Its called Proaganda, and the whole damn nation fell for it.

Anyways, have you been able to figure out what was the culpriet of the problems. I dont belive that changing the oil had anything to do with it. But, who knows. Any updates?

yes i do it every 2,300 its better to do it a little early than 3,000 miles i think.. by the way just becuase mobil says on the bottle 7,000 miles or whatever.. i wouldn't trust driving 5,000, 7,000 miles with the same oil. Well also another reason why I do mine every 2,300 miles is because the better you keep up with it the better and longer engine will last. Plus with my engine my engine gets really black fast for some reason so again that is why I do it before the 3,000 mark because I don't need to be having black **** oil staying in my engine for too long .

I was running Castrol Syntec 20w50 in my turbo Honda and changed my oil every 8500 miles. My oil only slightly darkened.

If your oil gets real black quick and you don't have good power. Then i would test the compression and a pressure test for the valve seals to see whats going on in your engine before blaming the oil.

[S13 240SX]

i'm not blaming the oil it just seems like royal purple is making it run like **** cuz i put a full syntec oil in a motor that has tons oil leaks and which i shouldn't of done but i wanted to take a risk and try it out.

Despite your best efforts - Royal Purple is not your problem. It is fine for stock motors.

[spank044]

Try some basic engine test to see whats going on with your internals. Trust me.

You guys should check out http://www.bobistheoilguy.com. Lots of good info.A funny thing with mobil1.. They did a test and turns out its not real synthetic... just overpriced group III... just like castrol whom they took to court for marketing their group III oil to be synthetic. Mobil1 lost, so they switched over to groupIII as well is the guess.

Just make sure if you are looking for synthetic, that it is a groupIV/V oil.

Additives like slick50 are Trash...

I'm torn right now between oils.RedlineEneos MotulRoyal Purple

AMSoil should be good too.

To the OG poster:Alot of the information you are giving is misled. I have to agree with tony that the 3k oil change is a waste of money and resources. Oil tech has imporoved and can go much longer but of course people still believe 3k is where you should change. Changing oil frequently certainly wont hurt anything on your car, but it will leave a dent in your wallet and the enviornment. How long you can go can be decided by having your oil analyzed. Analyzing your oil can also tell you what is going on in your engine. The way you describe your engine sounds like its not in topshape... I would look into other things beore blaming the oil.

[S13 240SX]

okay u guys really need to stop saying that i'm blamming the oil cuz i'm not.. all i'm saying is that I don't think it was such a good idea for me t run royal purple in my ****ty high mileage ka24de that leaks oil from the pain and front main seal, and valve cover gasket, i say that it probably wans't a good idea cuz sytneic oil eats away at bad seals and gaskets and makes the oil leak out more. Not blamming the oil!!!!! I'm saying and been saying I shouldn't of tired royal purple in my crappy high mileage ka but oh well that's my fault cuz i just wanted to try something different.

[S13 240SX]

and again one last thing... Oil tech has not improved... they want you to think mobile 1 oil can last 7,000 miles so more people will believe it and buy it!!!!

it's never good to let your oil go till changing it at 7,000 miles that's just bull crap talk for them to get people to believe it and buy it.

[paulie240sxr]

i agree its not the RP im running it in my engine, dif,transmission noticed a difference in it alright i had more power , if you have leaks i pay 7.00 a quart for mine thats alot of money to be loosieng and RP i can go for 10,000 miles before oil change filter every 3,500 miles in the long run its alot cheaper than your cheaper oils i think you have something else wrong with your motor and dont run sea foam threw it until you drain the RP out other wise your still wasting money , go down buy some cheap crap put it in there then run the seafoam in the crank case and drain then put the RP back in it

As to the statement about changing your oil longer than 3k miles being BS statement.. here is just a little food for thought.

My mom just recently bought a 2003 Jaguar XJ8 with 4.2L V-8.

The Owner's Manual states in it that the recommended interval for changing the oil in that car is once every 20k miles. IF oil tech has not changed, then why would a high end manufacturer like Jaguar recommend an oil change interval that is approximately 7X longer than the "accepted" interval? They aren't using any "Magic Jaguar Brand" oil. Recommended brand is Mobil1 Synthetic.

Also, if your motor is already leaking oil using standard petroleum based oil, then switching to a synthetic oil will only accentuate the problem. It sounds like you have bigger problems than bad luck with a quality oil manufacturer.

sounds like u have internal problem or clutch if u have one might have oil on it. synthetic can get by gaskets that are bad better than normal oils and number 4 might be your problem. this is going by what your are saying but untill it gets checked i can't say for sure

things to remember

1-running the engine cold(to many people run the car hard before warmup)2-idle time3-oil and filter4-engine condition

i'am a tech and not everyone is smart(75% of car owners are dumb)if you let your car warm up and use good oil and a good filter 5000 plus miles are not a problem. hell i've seen cars go 10K without a oil change because the owner was smart(and mostly highway driving). also if u have any leaking internal engine parts do not use synthetic because it is designed to get in to smaller spots for better lubrication and can get sucked into the combustion process easily or slip by gaskets.

I remember oil change on my first car. I forgot to put back the washer for oil pan plug and it leaked oil until the engine overheated and broke the steering belt. Luckly that was the only damage and I was right next to an autoshop.That 1.5L Hyundai also leaked oil like crazy and made new oil black in 1K miles.
