Best Annual Engine Oil Change

Protect your engine with a One Year oil change.

For vehicle owners in Canada and the USA, preventative car maintenance is a fact of life. For most makes and models, it used to be a set interval of three months or 5,000km (3,000 miles) between changing the motor oil. Modern vehicles might extend those intervals using semi-synthetic blend oil or with an oil life monitoring system, but at least two services are required per year. But did you know that a one-year oil change using AMSOIL can do the same job or better at protecting your engine?

AMSOIL Signature Series engine oils provide next-level protection against wear and tear when used in tandem with an EaO oil filter. Track your oil change history, receive maintenance reminders, and recall product information by creating a MyAMSOILGarage account.

For Ea filters carrying the product code Ea15K, the guarantee extends up to 15,000 miles or one year, regardless of the driving conditions. It’s advisable to change the oil filters every time you replace the motor oil.

Longer drain intervals, one year plus, can be achieved with oil analysis.

With oil analysis,  you can push oil change intervals to surpass one year and 40,000 kilometres (24,000 miles), going above and beyond AMSOIL’s standard intervals.
