Help me! Engine oil problem!!
 

My baby has been running on QuakerState Horsepower synthetic oil(5W30) so far, i paid $105 canadian dollar for 5 liters(60) of oil + oil filter(15) + labour(30) cost at autoshop.
Unfortunetly, i think this oil gets very hot(even while i'm driving like a grandma, oil temp guage hits 250F easily.) much too quickly than the stock oil from Nissan.
The temp at my area is nearly 90F everyday. Also, if i drive like an ***, oil temp gets even hotter than 250, then i can see somekind of black power on the dipstick.
Is this mean oil got burned?
I thought every single synthetic oil has better resistance on heat than the stock ester oil... Should i drain my engine oil and change to another one?
Does anyone have an experience of using Quakerstate synthetic oil on your car? Do you have any recommendation on engine oil?
Plz help me! :p

Top of this forum has a Sticky thread for engine oil temperatures. That should answer most of your questions. As for your dipstick finding and the quakerstate, perhaps someone else has an idea. The quakerstate is definitely not one of the oils most people have been discussing on this site, but if it meets the manual guidelines for oil specs it should theoretically be fine.

According to comments on sticky thread for engine oil temperatures, it seems nissan ester oil is better on high oil temp than most synthetic oils in aftermarket. Is it ture?

I haven't noticed a significant change in temps with the sythetic, im using mobil 1 though.

If it's all blackish. It's no good.
Lol.......stop street racing.

Quakerstate is one of the worst brands of oil out today. If you want one of the best bought oils on the shelf, get Penzoil Platinum. So far on all the tests from the labs, it has done much better than all of the competitors other than Amsoil. Mobil 1 is way down on the list now since they reformulated their oil.

If you want sound advice, I suggest go to www.bobistheoilguy.com and discuss the oils there.

An affordable one is Castrol Syntec.


What's with the urban legend that new cars don't need sythetic oil.
Only when it gets old. It's a good idea.

I thought higher mileage cars would benefit from it mostly and newer ones don't as much. So not worth the extra money. Once you synthetic, you can't go back to regular.

If you are seeing black residue in the oil after a short time then yes, the oil is braking down. All synthetics are not created equal, some are only 10% synthetic yet still call themselves synthetic.

I would stick to the oils that people have tested successfully for now.

I never used QuackerState...lol

My lawn mower gets better oil than QS oil.

hmmmm... i think i need to drain this retarded priceless garbage oil and get
Pennzoil(good price, Quaker was more expensive than this) or AMSoil(too expensive though...) thx for advice NISMOZ.
Should i stick to 5W-30? or is it okay if im using other than 5W-30?(ex,5-40 or 0w-50 etc)
Do i need to change oil filter? I've only used new oil and filter for 800miles. My oil is already breaking down? F***
I want my money back!!

I would recommend you use Nissan's recommended ester oil (which is a Penzoil Platinum product). I suspect you'll find your engine oil will run a bit cooler and your engine a bit quieter.

It's my understanding that Nissan has a service bulletin out on this and is recommending this oil for all Nissan and Infiniti vehicles that use the 3.7L V6 engine.

There are some good technical write-ups regarding why this oil is better for the engine so as I'm not an engineer and as the info is already available elsewhere I won't go into it here.

thx for advice ^^ i will get penzoil platinum this week!

QS in rotary
 

Back in the 90's my parents had an RX-7 and the factory recommended QS. The techs said that it was thinner than the other oils on the market and was better suited to the rotary... Maybe that is the problem in a high compression engine, too thin. Interesting?

$20 bucks at Walmart for 5 quart jug of Penzoil Plat. Good stuff. I would recommend doing the filter anyways since you might have a sludge issue and it's already in the filter. I would only use the weighs Nissan recommends for your engine. 5w30 is good.

There are several different varieties of Penzoil Platinum so I sort of question if the $20 jug would be the right type.

The right variety (that includes the ester oil) needs to be used to get the benefit.

Where did you learn that Nissan Ester oil is a Pennzoil Platinum product?

Where did you learn that Nissan Ester oil is a Pennzoil Platinum product?

A local Nissan dealer where I had my oil changed using Nissan's brand...the service manager provided me a coupon that will give me (I believe...I don't have the coupon in front of me) a $50 rebate after a specified number of oil changes (four I think) from Penzoil for using a Penzoil Platinum product.

Do you think it has a direct commercial counterpart or do you think that Penzoil is producing a customized oil for Nissan?

I honestly do not know but I would be surprised if the blend Nissan is selling isn't some sort of "standard" Pennzoil Platinum product.

I was surprised when my dealer's service manager handed me the rebate coupon but I have to conclude that the "Nissan Ester oil" is at least some version of Pennzoil Platinum synthetic.

Your oil has broken down(some kind of black power on the dipstick), "it's no good"! Get it out as soon as possible>preferably don't drive it, until after you change the oil!
Now for the bad news! That crap on your dip stick, is still in your engine . After you change your oil&filter, to a good synthetic. Drive a 1000, 2000 miles,"do not go the recommended 6000 or more miles"! At 1 or 2K, change your oil&filter again. You need to get the crap from the old oil, out of your engine.

Sorry but there is only one Penzoil Platinum. Only one Mobil 1, etc. There are no differences between a Walmart 5 quart jug and a Autozone 5 quart jug.

After doing a little more research, it appears that Nissan holds a patent on the "Nissan Ester Oil" the dealers sell so it may well be that Pennzoil actually does make the oil specifically for Nissan (hence why you can participate in the Pennzoil rebate) and that it isn't a standard Pennzoil product so at this point, I wonder if "Pennzoil Platinum" is the equivalent of the Nissan branded ester oil.

It appears that a basic requirement for an "ester" oil is that it belongs to a "group V" synthetic (and not all synthetics are group V)...whether Pennzoil Platinum is or isn't an ester based synthetic I don't know and haven't been able to find out; even on Pennzoil's website.

If the base oils are the same then I believe the esters can be added during manufacturing easy enough. Some of the descriptions on the Penzoil website were similar to the Nissan ones but it was by no way definitive.

Need the oil doc!

Maybe someone just needs to contact Pennzoil directly (through their website) and ask. :)

Try castrol or royal purple. I hear that Penzoil is crap.

Where did you hear that Pennzoil is crap? Is there are any proven issue on that certain oil?:shakes head:

which castrol oil do you recommend?, I couldn't find castrol Edge at my area.... only regular Castrol synthetic is available...BTW, I heard Royal purple is one of the best engine oil at the market, but not with nissan VQ engines. Is it true?:confused:

You heard wrong. RP is actually crap. Read the site I recommended above to learn more about oils and tests that have been done on all the new ones.

Penzoil Plat is one of the best oils out now and it's only $20 bucks!

Castrol Edge is overpriced. Walmart has it for around $34 for a 5 quart container. When you can get Penzoil Plat for $20 (5 quart jug), M1 for $22 (4 quart jug), Castrol Syntec $25 (5 quart jug).

Royal Purple is one of the worst oils you can get.

Truth in Advertising: BP v. Royal Purple

+ all the tests done on bobistheoilguy.com forums.

Pennsoil and Nissan ?
 

Would be interesting to follow up on who actually makes Nissan ester. I don't believe for a minute that Nissan makes is but does hold the patent. Got some good stuff on bobistheoilguy.com on Nissan ester oil. However, no one is sure who makes it. It is not common enough to generate a lot of interest. I am sure with a little digging that someone will discover the maker and how much ester is has in it. It could be only a small %. Like some oils that advertise being synthetic but only have a small amount of synthetic base stock. Ester is not new. Amsoil makes their compressor oil with it. I would imagine that any good group IV or above would do very well. Will do some digging and see what I can find.

yeah, engine sludge sucks big time........ ever saw the Castrol commercial with the oil falling on a person...... that's what you got :icon14:

Castrol seems pretty good, i never had a problem with it.

lol......reminds of what i did...... one day i decided that no more maintenance or repairs on my grand-am...it took like 25K km to turn regular Castrol oil into foam... :ugh2: then it went to the scarp yard.

Now, don't get me wrong. I sell Auto Parts for a living. Quaker State was bought by Pennzoil about 4 years ago. Our reps in Canada have told us that the product in the bottle is exactly the same. In fact, they were bought by Shell Lubricants about 2 years ago and I wouldn't be surprised if all three brands had the same stuff in the bottle. (You know, oil.... it's all about marketing.)

FYI

so Penzoil is no good??.....yea yea.....i said no good like my user name

It isn't the same stuff as tests have shown. Penzoil Plat is much better quality over Quakerstate. This has been discussed on the site above.

Isn't Quakerstate and Penzoil the same company? - Bob Is The Oil Guy

Watch this topic. They are the same company and Penzoil Plat is a different product and much better.

Seriously, do your engine a favor and AT LEAST put some Castrol Edge in there. If you can afford it, Royal Purple is the way to go. If not, consider Motul or Mobil 1.

The claims of Royal Purple being one of the worst oils you can buy are a bit extreme! The article that you linked simply shows that in the test that was conducted Royal Purple did not display any signifigant differences from the other oil it was tested against. Never did they say that it was a bad oil or bad for your vehicle, they only said that many of it's claims were not up to par. It is still a solid oil choice and I've had great results with it in my previous vehicle, so based on my personal preference I say if you are willing to pay for it, use it! But with that in mind going the advantages of Royal Purple are not that signifigant enough that would make it really worth using over another high quality synthetic like Penzoil Platinum. To each his own tho!

I actually JUST got back from getting my oil changed and I used Royal Purple this time! (3k miles oil change) I have a 1500 mile Road trip I'll be making over this weekend and plan to see how things turn out for me with the Royal purple. Next oil change I will be going with the Penzoil Platinum to see how it works out for me as well, and will then be basing my long term oil choice off my own personal experiences after trying both oils in my Z. Thats the only real way to determine whats gonna work for you!

That is just a article. All the actual lab tests are on BITOG and you can find them there where they did not do that well on most cars.

Castrol GTX Dino oil out performed RP and it's not even a synthetic. RP has such high wear, and metals showing in the oil changes vs other oils it is scary.

Just by trying it and saying it did well without a lab test results done on the oil is a bad comparison.

My family has been using Royal Purple lubricants in marine racing applications since the 1980s. It is hardly a hype. It is excellent oil. You're basing your knowledge on a bunch of experts from BP Lubricants and RP doing biased, unscientific tests on eachothers' products.

Do you even know the difference between regular and synthetic oil?
