has anyone used the new 0w-30 Mobil-1 . i was reading the jug at walmart the other day, it says it exceeds all 5w-30 and 10w-30 specs. and gets you better gas mileage. any ideas???
When it does get down to that -50F here, I found it vital to have a full synthetic 5w-30 and a good battery for the car to start without a block heater. Dino oil gets waaaay to thick. As for using a 0W-30 weight oil, I don't see how it could hurt too much.A 0w30 oil could be used year round if you wanted to, but since it usually costs more most people don't bother. I've used amsoil 0w30 for around 35000 miles and haven't had any problems (140000 miles on the engine), but just switched to the german castrol 0w30 (red label) because it's cheaper and easier to find. If you don't have cold winters a 5w30 is good enough, I live in Canada so it can get pretty cold some mornings during the winter. I've started my car every morning without using the block heater (nowhere to plug in) for a full winter when I was living in the Northwest Territories and it started every time, with temperatures as low as -51F without the wind chill, lower then -60F with. Glad I moved from there, now it only gets down to -35F where I live now. Also a big misconception with 0w30 oil is that it's too thin of an oil, but at full operating temperatures it's a 30 weight oil anyway (hense the 30 at the end of 0w30), but performs like a 0 weight when cold. That's where the added cost of the oil comes in, because you can't get a 0w30 that isn't fully synthetic.
Just an FYI
Keep in mind that the 0W or 5W of dino oil is the base and viscosity modifiers are used to get to 30. So the wider the spread the more viscosity modifiers are used. More additives could mean quicker break down. So whatever you use change your oil as recommended. Synthetic is a different animal.
Thats not quite right. The oil starts out as a base oil. Viscosity modifiers are what create the weight of the oil in the first place... Ie. bringing it to a 30 weight. Then other types of viscosity modifiers are added to create oil that performs like a 0 weight or 5 weight at colder temperatures. The oil does not magically morph into 0 weight or 5 weight when it is cold, it just does not thicken like a straight 30 weight, the amount it thickens is slower.
Also synthetic oils are the same as dino oil. The difference between synthetic oils and dino oils is that natural oil is made up of carbon chains ranging from 40-80 molecules long. Synthetic oil is also made up of the same carbon chains, however these chains are all uniform length. So in a full synthetic oil you would have all the chains say 65 molecules long. Equal length chains make the oil more stable molecularly which means there will be less trading of molecules between chains. The even length also makes synthetic transfer heat more evenly as a longer carbon chain retains heat longer and a shorter chain retains it less. The equal length causes all of the chemicals added to the oil to stay in suspension better because the chemicals can bond evenly and equally to the carbon chains. These properties are what lead to synthetic oils lasting longer and being "better" for your engine. The heat dissapation properties are one of the biggest benifits for your engine. And since the synthetic breaks down at a slower rate and holds additives in suspension better you get more predictable performance in your oil.
Just out of curiosity... Are the oil discussions ever gonna die on this site???
No, I don't think that the oil discussions are going to stop on this site any time soon.
If you follow what your owners manual says,change your oil regularly, and drive like an adult your engine will last at least 200,000 miles. Go to a high milage blend when your milage is higher and if you are starting to burn oil. Change your oil regularly, synthetic and semi synthetic increases your service intervals. Change it every 3000 miles if you do most of your driving in town, you can go as much as 7500 miles if all of your driving is on the highway.
