Wrong Oil! HELP!!!

[Alexsered]

I know, the answer is no. **** people are humans they make mistakes, and this one is not a big deal for anyone to get their panties in a bunch over. Stop with the crying and worry about something that actually matters.

there was a thread somewhere on hear about people having seal problems on their turbos and them using 5w20. There were also some people that had their turbo's smoking but once they switched to a 5w30, the turbo's didn't smoke anymore. I know enough about oil, and I would never put 5w20 in a turbo'd car, I started with 5w30 and now am with 10w30.

this s***'s been in there for 5k, no smoke. i just realized this last week or the week before.
instead of 10-30, which only makes the oil thicker when it's cold...one should try 5-40

10w30 isn't just thicker oil in cold temperatures..Do some research and then report back .

The same thing happened to me when I brought mine in for a change. I called up and asked about it and they told me the tech knows to put 5w-30 and the receipt is generic. They told me not to worry and that 5w-30 was used. I don't know how much truth there was, but these guys are the top rated dealer around in customer satisfactory so I would think if they ****** up they would make it right rather lie about it. Next time i'm bringing the oil in myself unless weather permits self service.

cold temps outside?
no, i mean when the oil is cold or warm.
also, i was comparing 10-30 to 5-30

The centistoke rating is converted into the SAE weight designation using a chart like the one shown on the Superior Lubricants Web site.

Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. This page from the Sci.Electronics.Repair FAQ offers the following very interesting description of how the polymers work:

At cold temperatures, the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up, the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C, the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot.

The viscosity is different. The 10w is the cold viscosity, 10 being thinner than 20. The second number is the hot viscosity, 30 being thinner than 40. So at cold temps these oils will flow the same. At hot temps the 10w-30 will flow easier than the 10w-40.

did we misunderstand each other?
or are you just wrong?

wow...Relax....

I wasn't quite referring to temperature affects only, there has been quite some research done on testing different types of oil weight, some studies show that 10w30 contains higher-grade detergents and does not degrade oil viscosity over 3-4K miles on a pig-rich engine like our 2.3 DISI engine...This was compared to 5w30.


I for one am a firm believer that the above statement is true, I used to use 5w30 and compared it to 10w30, my 5w30 oil seemed to smell like fuel and when checked for consistency, it looked like 5w20. 10w30 oil on my car after 4K miles had no fuel smell and consistency was in check.

Now it's time to test my 10w40
Thanks.(wink)

cool. do it

The W stands for Winter not Weight.

I'm sure everyone already knew that....(ugh)

there is a maximum "weight" our turbo's bearings can handle, if I remember correctly I think it was 40. There was a long write up on a website and I promise that as soon as I find it, I will post it. But it was refering to the turbo model, not the engine model.

I talked to my service manager today and she said that even though the stickr says 5W-20 my car has always had 5W-30 put in it. She said that 90% or more of the cars that she deals with take 5-20 and that they simply dont change what is printed on the sticker. She assured me that the tech would write on the paper work that my car recieves 5-30 each time I come in for an oil change. That still dosint make me 100% confident that Joe Blow in the back is putting 5-30 in my car. But its good that she knows now I guess.

On any forum - I doubt 20% of those on any car forum know the W stands for Winter and not weight

Riiiiiggghhhhhhttttt.
