Synthetic oils are created by breaking down crude oil on the molecular level and rebuilding them to a specific innate and uniform structure, which nearly eliminates deterioration. Viscosity refers to a liquid’s ability to resist flow – essentially how thick or thin it is. Honey is considered to have a high viscosity, whereas water has a low viscosity. Motor oil with a low viscosity is able to seep into the tight spaces between the components inside a modern motor. But it might have a tough time holding up to the heat and filling the wider gaps of an older engine.
Castrol EDGE Euro Car product range has been optimized to meet the stringent requirements of the various European Automobile Manufacturers Association or ACEA oil sequences. These standards can apply to both gasoline and diesel powered engines and are often more demanding than ILSAC/API requirements. Synthetic and conventional oil both start life as crude oil. Conventional oils use additives to achieve the desired viscosity range, but when those additives deteriorate, the oil’s ability to adapt to changing temperatures is diminished.
As the cost of synthetic oil drops closer to conventional oil, remember that some engines are still better suited to conventional oils. Older vehicles or engines that have run on conventional oil for hundreds of thousands of miles may need the specific additives included in conventional oils to prevent leaking seals. Rotary engines in particular require conventional oil, andMazdaspecifically recommends against using synthetic oil in models like the RX-7 and RX-8.
High mileage formulations of conventional, synthetic blend and full synthetic engine oils contain additives which can condition seals, helping to prevent leaks, and also fight sludge. As engines age, piston rings and other internal components can seize up. Special detergent packages in high mileage oil blends help keep engine components moving freely, improving oil flow and lengthening the life of an engine.

If a signature is required please inspect your package carefully before signing for it. If after accepting the package you determine that there are damaged or defective parts, please contact the manufacturer for replacement parts. Do not discard the boxes or packing materials, as they may mobil 1 oil be needed to ship the item back. We regret that BJ’s cannot cover the cost of shipping for products returned due to buyer’s remorse.

More than the brand, the motor oil’s viscosity grade is of greater importance when choosing between Amsoil and Mobil 1 products. In essence, both offer the most common oil grades from 0W20 to 20W-50. Depending on the type of oil blend recommended for your vehicle, some variants may only be available through one of these two brands.
We specifically chose highly-rated and readily available motor oils that are compatible with a wide range of vehicle makes and models on the road today. Each product is rated on quality, durability, vehicle compatibility, and protection from wear and sludge. Interestingly, many vehicle owners do not believe in the credibility of this test, as its parameters do not capture real-life causes of engine wear. Using 0W-30 motor oil on engines in sub-zero weather would be subject to entirely different conditions and triggers for viscosity loss compared to that of the test. RPMs are also controlled, with a ceiling of 1,800 revs. Finally, consider the cost per quart when choosing between Amsoil and Mobil 1 synthetic oil brands.
