The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.
Longer hydrocarbon molecules have a stronger intermolecular force. More energy is needed to move them apart so they have higher boiling points . This makes them less volatile and therefore less flammable .
Fractional distillation is used to separate crude oil into useful liquids that have different boiling points. Petrol and diesel are useful fractions of crude oil.
(ii) Methane is one of the gases obtained when crude oil is separated.
It is common to have small amounts of gasoline and distillate (kerosine or diesel) mix together in pipeline transportation. It also occasionally happens in barge and truck deliveries. The only way to separate the two is to put them through a distillation column.
Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.
chromatography: Involves solvent separation on a solid medium. distillation: Takes advantage of differences in boiling points. evaporation: Removes a liquid from a solution to leave a solid material. filtration: Separates solids of different sizes.
Another common separation process is called distillation. Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points. For example, if you heat salt water the water in the solution will boil before the salt.
The chance that there is some overlap between your two oils is big, so the answer to your immediate questions likely is no, completely impossible. Don’t mix two oils and try to separate them afterwards. 😉
Yes, you can safely mix one brand of oil (e.g. Mobil 1) with a different brand (e.g. AMSOIL) or conventional oil with synthetic oil (in fact, that’s what a synthetic blend is). Most synthetics today are fully compatible with conventional oils and can safely be mixed.
Yes, if topping up. If your oil must be topped up, then you are burning oil already, so the difference won’t cause more damage than is already there. 5W30 and 10W30 are essentially the same at operating temperature. It is only for cold weather starting that the performance will be different.
Here at the Mike Young, we use ACDelco conventional oil, ACDelco dexos synthetic blend and Mobil1 full synthetic oils as specified by General Motors for your GM vehicle.
Ed Morse Sawgrass Chevrolet Service is pleased to announce that GM vehicles requiring Dexos 5W30 synthetic blend oil will NOW have the upgraded formula DEXOS 1 5W30 FULL SYNTHETIC OIL installed at NO additional cost.
Both dexos and GF-5 oils allow more miles between oil changes without a loss of lubrication qualities, sludge buildup or damage to the catalytic converter. Depending on your driving habits, oil changes could extend beyond 10,000 miles. Ask for the proper oil when having it changed.
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles. Moreover, if your car’s engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!
Dexos oil is engine oil that meets a special set of requirements. Dexos oil is also specially formulated for proper lubrication, sludge reduction, friction level moderation and controlling temperatures – the latter being especially important in vehicles with turbochargers or superchargers, as they create more heat.
All vehicles produced in and after 2011 are stocked with Dexos oil and are recommended to be used for the life of the vehicle. Dexos can also be used in older models of GM vehicles and is a certified and licensed product of General Motors.

of Substitute Engine Oils if dexos is unavailable: In the event that dexos‐approved engine oil is not available at an oil change or for maintaining proper oil level, you may use substitute engine oil displaying the API Starburst symbol and of SAE 5W-30 viscosity grade.
In addition, ExxonMobil announced that a number of its key products, including Mobil 1, are now officially dexos licensed worldwide. Part of the offer will be Mobil 1, the world’s leading synthetic motor oil brand, with Mobil 1 5W-30 for dexos1 and Mobil 1 ESP 0W-40 for dexos2.
Can I use either? No! Even though many of the features are very similar, dexos1 oils are designed for gasoline engines and dexos2 for diesels. Due to the inherent differences in operations between gasoline and diesel engines, using the intended oil is of the highest importance.
Pennzoil Platinum is designed to provide the ultimate protection under the most severe driving style and conditions. Because it’s DEXOS-1-approved Pennzoil Platinum full synthetic motor oil is the ideal choice for many applications.
