I see WW has mobil 0W-30 and 5W-30 for same price. $22/4.75quart. my new car uses 0W-20 so it looks like both of my cars will have 0W oil this winter. i park outside so i need it. dino oil is $10-12 for the same amount. why not use syn? you know any wear on internal motor parts can never be restored without an overhaul.

This confuses me are you trying to tell us what to do or are you asking. All I know is I laughed through it so ya lol

huh?

0W? are you nuts?

0w works fine in the winter.

As long as it's a multi-weight.

i hate starting oil threads since everyone has their own opinion on what works for them. i was just wondering what the ratio would be to folks who say syn oil is a waste of money vs those who like it. i think syn oil flows better in winter. if i am going to spend extra money on syn 5w-30, than why not get 0w-30 since it costs the same. just wanted to see if anyone else uses 0W oil.

Uhh, how about the people who live in canada where the temp is below 0 the whole winter? I know for sure I saw in the owner's manual somewhere that 0W-XX oil can be used, but I believe it said something like ask your dealer first

When I lived in Maine I ran 5w-30

haha, we haven't really had consistent below 0 weather here in Windsor, all the way up in Canadia.

This thread = Teh Fail

The 0w-30 is fine. It will allow your motor to spin easier and pump the oil easier while it warms up.

The following is from Amsoil's website.


We get asked this question so often that we have included this special page dedicated exclusively to answering the question.

AMSOIL 0W-30, 5W-30 and 10W-30 synthetic motor oils are ALL 30 weight oils. The answer is that ANY one can be used regardless if your vehicle owners manual says to use, for example, a 5W-30. "W" means winter. In winter weather the 0W oil will flow like a 0W oil, and the 5W will flow like a 5W oil and a 10W will flow like a 10W oil just until the engine warms up. In order to understand the differences one has to first understand that the numerical values given to these various weight oils are strictly empirical numbers. For example, 0W does not mean that the oil has no weight. That is one of the reasons why we say it is strictly an empirical number.

In order to determine the differences between the three oils one has to look at the kinematic viscosity of each lubricant. The kinematic viscosity is essentially the amount of time, in centistokes, that it takes for a specified volume of the lubricant to flow through a fixed diameter orifice at a given temperature.

Let's compare the kinematic viscosity of the three AMSOIL lubricants

AMSOIL 0W-30 is 57.3 cST @ 40 deg. C, & 11.3 cST @ 100 deg. C

AMSOIL 5W-30 is 59.5 cST @ 40 deg. C, & 11.7 cST @ 100 deg. C

AMSOIL 10W-30 is 66.1 cST @ 40 deg. C, & 11.7 cST @ 100 deg. C.

As you can see from the data above the kinematic viscosities are extremely close. Therefore, whether you use the 0W-30, 5W-30 or the 10W-30 is strictly a matter of choice. With the small differences in kinematic viscosity you would be hard-pressed to detect these differences on initial engine start-up without specialized engine test equipment.

All three oils are excellent motor oils and ANY one can be used in a vehicle which requires either a 0W-30, 5W-30 or 10W-30 oil as well as in several other engine applications including an engine which recommends a 5W- 20 oil.


This leads to the next topic: many people also ask us if the 0W-30 is too thin a viscosity oil for high ambient temperature operation. The answer is absolutely not! Thicker viscosity oils are not always necessarily better since in addition to its' various engine lubrication functions, an oil must also effectively transfer heat. Only about 60% of an engines cooling is performed by the engine coolant, and only on the upper half of the engine. The remaining 40% of an engines cooling is performed mainly by the engine oil.

Although a vehicle that is recommended to use a 30 weight oil can also use a 40 weight oil, it is usually not needed. You will gain absolutely no benefit from using a thicker viscosity oil if it is not needed. The only time we recommend a 40 weight oil, such as AMSOIL's 10W-40, to a customer in a passenger car or light truck application is if the vehicle's engine is excessively worn and consumes oil at a higher than normal rate or if the vehicle is being used for very severe duty, high load, high temperature applications.

Yeah, the manual says to consider 5W30, or even 0W30 when it will be below -20...

Temps drop below -20 here, but I just went with 5W30.

40F is nice. whats the viscosity at 0F or -10F? viscosity doubles for every 10F temp drop.

sorry for off topic.. holy crap. Wonder what is story about that? I see it is from MTV logo which I'm not surprised about that. It is always drama show that my ex-gf love to watch it. I see glow color tag on wrist like 21 up or underage for beer. It looks like from club. This guy probably arrest for that? I mean you can't hit that girl like that. Dang poor girl. She probably got pain face few days. This guy face look soo priceless. He just like *turn around* "are you talking to me? *punch* I think he actually punch guy in middle too? Hard to tell from this angle.

Back oil topic... I actually have owner manual book on my desk with me. I see it show 5W-30 or 10W-30.

The note "For best fuel economy and cold starting, select the lowest sae viscosity grade oil for the expected temperature range.

I never seen any 0W oil in store. I guess it was new?
