If the vehicles in your fleet require synthetic oil, you may be keen to know how often this type of oil requires refreshing. Unlike conventional oil used in cars, synthetic oil is highly refined, enabling it to increase engine performance, lower friction and reduce sludge build-up.
To ensure that a synthetic oil can deliver these benefits, experts recommend that changes take place every 7,500 to 15,000 miles, although this will depend on the synthetic oil brand and the type of vehicle in use. To make certain you are always changing your vehicle’s oil at the correct intervals, the best practice is to check in your owner’s manual for full information on any requirements unique to your make and model.
To learn more about when you should change over synthetic oil and what the difference is between standard and synthetic and oil, read on below.
How do synthetic and conventional oil differ?
Conventional engine oil is refined directly from crude oil, while synthetic engine oil is a man-made product created using chemical compounds developed to feature the best qualities of crude oil. For this reason, highly refined synthetic oil is often more expensive to purchase, but offers a sound return on its investment. Being highly refined, synthetic oil includes far fewer contaminants, so engines experience less sludge build-up.
Why does synthetic oil need to be changed less often than conventional oil?
Some cars and trucks using synthetic oil can run for 15,000 miles before needing a change. This longer oil change interval is provided due to the refined properties of these man-made products. Synthetic oils also operate better at high temperatures compared to their conventional counterparts. Unlike standard engine oils, synthetic solutions do not thicken when exposed to excessive heat.
Synthetic oil applications
From racing cars and motorcycles to heavy hauling trucks, high-performance vehicles often rely upon synthetic oil for its long-lasting nature and its long change intervals.
However, it is worth noting that it is generally not recommended for users to mix different types of engine oil, especially different grades such as conventional and synthetic. As a rule, when oils are mixed, the advanced benefits offered by the synthetic oil are effectively diluted and, in some cases, even negated. For instance, those looking to enjoy longer oil change intervals will find themselves due for a change much sooner than when they only use a synthetic solution in their vehicle.
