Oil viscosity vs temperature

Why would you assume that 5W-30 is somehow lighter at cold temperatures than 5W-40? The 5W is the cold viscosity. The 30/40 are the hot viscosities. The cold viscosities look the same to me.

If I go to this tool http://www.widman.biz/English/Calculators/Graph.html and graph the oil I am currently using (Schaeffer 9000 5W-40) vs Liqui Moly Top Tec 4200 5W-30 (507 approved) I see that at 0 C there is a substantial difference in viscosity (approx. 720 vs 550 CSt). On the other side the viscosity differences at hot temperatures (around 100 C) are much less pronounced.

I think if a 0W-30 507 oil was available in North America the difference would be even more noticeable.

The 5W characterizes the cold performance. It doesn't matter whether it's 5W-30 or 5W-40; both have to fall into the same 5W classification for cold performance. Obviously, 5W covers a range, so not every 5W is exactly the same as any other 5W.

The 40 or 30 or even 20 has nothing whatever to do with cold performance.

In theory I agree with your statements. I was trying to use the graph tool to understand the cold temperature variability between two oils based on the published viscosity properties (using either ASTM D-445 or DIN 51562 methods). Using this tool it seems to me that at 0 C the viscosities are sufficiently different to impact how fast the engine would circulate throughout the engine in a cold morning start (for example).

Fairly said. I can't get any traction whatsoever on that graph page, and the underlying calculations and extrapolations are not evident. If you don't mind helping me, how were you able to enter your changes, and what was the raw data you entered?

Bottom line, I highly doubt if 550 vs 720 CSt at 0 C would make any significant difference in cold circulation, but it's your car. I know I am mighty OCD about my own car.

I note that Amsoil HDD has a pour point of -60 and DEO is -46, although they are both 5W. I am definitely going to go back to HDD on my ALH, though that is mostly for the vastly superior 12.4 TBN.

The page needs Adobe Flash to work. I just input the Viscosity cSt at 40°C/100°C that you can normally get from the Technical Data Sheet (TDS) and chose the minimum temperature = -5°C Here is the result:

AMO or HDD in Cr 2.0?

Hello,

Is anyone running the AMO or HDD in cr 2.0 with dpf removed? Any oil analysis? Thanks!

 

[iamatt]

Answering my own post and putting my own skin in the game... Rolling the HDD 3000 series in the CR 2.0 Oil analysis after 5-7K and see where we are at!

 

[jrm]

I threw a quart of both AEL and AFL into my freezer and the 5w30 AEL was slightly more fluid when given a good shake. I still use AFL in my 2013 Passat FWIW
Just renewed my fathers old Amsoil dealer status, he flew F series jets with AL and was one of a handful who sold AMZOIL back in the mid 70's
He got 900,000 miles out of a old Chrysler 360 using Amsoil from the start

Mobil once took an E30 BMW 325i, filled it with Mobil 1 synthetic and ran it at 85 mph for four years straight on rollers with a constant fuel supply and no more than the standard owners handbook schedule. They stopped at a million miles.

When the engine was disassembled and measured it was found that it had not even worn beyond the assembly line specification. It was within the engineering tolerances of a new engine, essentially no wear. That old 360 might have gone a lot further on Mobil 1.

The big test though is Irv Gordon's record breaking 3 million+ mile 1966 Volvo. Not one drop of synthetic, every mile on Castrol 'dino' oil and all maintenance done according to the manual in the glovebox. No more, no less:

Irv Gordon's tips for 3 million miles:

"I service it as the owner's manual called for ... figuring the manual was written by the engineers who built the car ... who knows better than they do?

Unfortunately, I do not have a garage for the Volvo...never did. The P1800 has been outside for 41 years and continues to live in the elements ... just a block or two from the ocean and its salty winds. The car is driven daily summer and winter, through snow, ice, rain, etc. It has never failed to take me where I wanted to go and never broken down en-transit. I guess those engineers really knew what they were talking about regarding service schedules."


Perhaps the most important tip: "When your car makes a funny noise, listen to it."

I don't have time to read a 100+ pages....I have used Amsoil European Car formula that I used in my 1999 Jetta MkIII with no issues. I have a case of the stuff and now I have a new to me 2011 Jetta MkVI TDI. Can I use this oil in the 2011?

Thanks for any insight.

I'd be curious what your owner's manual says compared to what Amsoil Euro 5w40 is specified for. You don't have to read this thread. Is Amsoil Euro 5w40 recommended for VW 507.00?

 

[20IndigoBlue02]

Amsoil euro 5w40 not suited for 507 applications

euro 5w30 (AEL) is for 507 applications


Sent from my iPhone. There may be horrible grammar and misspelling involved

 

[TDIPeter]

Okay thanks for the info! I will use what the dealer gave me...Castrol Syntec 507.00. I have a case of Amsoil 5w40. Maybe I can get it exchanged back for the Amsoil 5w30 AEL you mention.

 

[FXDL]

I have a 2010 TDI and as far as the 504/507 oils go what is so special about them. My next oil change will be Amsoils 5W30 HDD diesel oil. Their HDD is better then any of their other diesel oils. Why you ask because I want the oil that allows the least amount of wear and I believe Amsoil's HDD is the best choice and best diesel oil out. I also want to get my hands on a Pure Power Billet oil filter and get rid of the paper oil filter. Each their own. Use what makes you happy and one believes to be best.

 

[FXDL]

Why is only 2 Amsoil oils being polled, why not more of them?

In 2006, those were the two most common permissible oils for TDIs.

This has the general overview of 504.00/507.00: www.nulon.com.au/pdf/FS121%20-%20EURO504-507-specification

HDD's SAPS and NOACK are well outside what CR TDIs were designed for. If you have removed your emissions equipment, this is not an issue.

What does that mean? Any oil would probably "hold up well " in a car as new as yours. Also coming from an Amsoil dealer. Give me a break! man you guys really like to smell your own farts.

 

[fnj2]

Anybody running >50% biodiesel in a VW common rail diesel is living dangerously anyway.

From oil analysis. Don't fly blind. Over 30K on HDD and various blends of Bio.

30K ain't nothin' Let us see it! Don't just talk walk the walk.

Agreed and I would ask why? Diesel ain't that expensive.

 

[TooSlick]

Iamatt,

Amsoils recommendation if you're using more than 10% biodiesel is to stick with the manufacturers recommended change intervals. Due to the much higher flashpoint of biodiesel (vs #2 diesel), it's possible to see excessive fuel dilution of the engine oil. It's a particular issue with short trip driving in cold weather.

I'm curious what sort of fuel levels you're seeing in your analysis reports?

TooSlick, welcome back!

Hope the absence was travel related and not a health issue.

[GreenLantern_TDI]

Iamatt.. 30,000 miles on an oci i would love to see the uoa as well. If amsoil hdd is that good we all need to know.

 

[XFIRE]

I just remembered .....

After reading a couple of pages of this post, I alarmingly remembered why I don't sit home at night and read forums.

 

[kevinbud]

Amsoil looks to have new formula for AEL. Seems to be more robust package with noack of 7.1 and tbn of 8.8. Ironically the 5w30 has slightly higher base number than 5w40. Is Amsoil using Ashless tbn enhancer or is this oil likely mid saps oil that will likely protect better and go longer but have like 8% sulphated ash. My 2011 tdi golf has 208000 on it now. Have generally changed oil on average at 7500 miles never added makeup oil even when extended to ten thousand.

2010 TDI 6 speed manual Trans.
Anyone using Amsoils synchromesh trans fluid in one and how do you like it, compared to GM's synchromesh ??
GM's is semi syn., and Amsoil's is 100% syn..

 

[kaylabryn]

Just changed to Amsoil's Synchromesh a month or so ago. So far so good, shifts better than before (104K on original I assume). Mileage is up a tick maybe, 38.5 before mixed driving now 39 or so, but only have 3 or 4 tanks with the new stuff time will tell. Price was not too bad, I think I paid $35 for 3 quarts.
