Oil change time!
*putting on flame suit*
Please indulge me![Big Grin](https://acurazine.com/forums/images/smilies/biggrin.gif)
I don't drive a ton.... car has 58k miles on it.
Chicago weather is pretty nasty... normal winter days is probably mid teens (F) but can drop to the single digits.
I'm currently running Mobil1 10W30 and am inclined to use the same.
I've thought about trying Amsoil or RP but eh, I need to get my oil changed soon so I'd rather pick up some Mobil1 at WalMart for ~$20.

Guys, look at facts here. The SAE charts say it all.
Synthetic 10-30 is good down to 0F and then some.
That's why I run a straight synthetic 30wt in the TL since my temps never get below freezing. Looking at the specs, my oil should be good into the single digits, slightly better than dino 10-30. I get the benefits of a mono grade oil with the good cold weather pumpability.
Now if you do lots of short trips where the oil never gets up to temp (10 minutes or less), then by all means go with a 0 or 5wt.

In the negatives, don't use a dino 10-30.
A synthetic 10-30 will flow as good as a dino 5-30 when cold.
A synthetic 5-30 or even a 5-20 would be a great oil for your winters.
Temperature extremes is where synthetic shines.

The only difference in the oils you are listing is the weight the oil starts out at, being they are all multi-viscosity oils and all end at 30. Fact is....not gonna make a whole lot of difference in the end other than what weight it starts out at cold. Thinner is going to circulate faster under cold conditions...so its probably better to run the 0W30 as recommended as on the top end when its hot....protects the same as a 10w30. The 0w30 just circulates faster on initial startup....which in fact...is a good thing.

All else being equal, the less spread between the numbers the more shear resistant the oil is. A 10-30 is no doubt a much more robust oil than a 0-30 under hard usage.
I'm pretty sure any 0w oil is at a minimum partially synthetic if not fully synthetic. Dino oil cannot meet the 0w requirement.

Found a fun informative site that I have been reading for about an hour now....good stuff here...lots of answers to questions. Interesting read. And of course.....we are speaking of synthetics here....I didnt know anybody still used dyno oil anymore frankly. lolol

Question: Explaining Viscosity DesignationsWhat does 10W-40, 5W-30 etc., mean? I would really appreciate it if you could explain it in simple language so I can teach my students. There are so many different grades of oils. Which one is better to use in summer then winter (Chicago) and vise versa? Thanks a lot. -- Vijay Patel, Lake Zurich, IL![](http://www.mobil.com/USA-English/MotorOil/images/spacer.gif)
Answer: In simple language, the first part of the viscosity designation (W grade) is an indication of the product's ability to help an engine crank and start and for the engine to pump the lubricant. The lower the number (0W is the lowest), the lower the temperature the product can be used. So the W grade is related to the lowest temperature your engine sees when you start the engine on the coldest morning of the year. But also keep in mind that a lower W grade pumps and helps an engine to start better than a higher W grade. The second part the viscosity grade is related to the viscosity your engine sees at operating temperature. In this case, a higher number is a higher viscosity grade and provides more viscous oil at operating temperature than lower viscosity grade oil. It is not safe to assume that a higher viscosity oil is always better for your engine because other factors, such as engine design, fuel economy and power, are also related to operating viscosity. You should always consult your owner's manual for the right oil to use for your particular engine. For more information on the viscosity grade specifications, a quick search of the Internet will identify several Web sites where information about SAE J300 (Viscosity Properties Test) can be found.

Amsoil 0w20 in the cold where I live. No matter how cold the engine turns over nice and fast. Amsoil has the data to prove they are the best. Do some research and you will see.

Hmm...since were talking about oil changes, I'm due for one probably end of January. What do you guys suggest I use? This will be my first oil change with this car and I've used 10W30 in the past. I live in Toronto and sometimes temperature gets to about -20C to -30C. Right now its -8 outside but feels like -16 to give you an idea...any suggestions?
