Subaru Ascent Engine Oil & Fluids

If you own a Subaru Ascent, then you know that the engine oil in your vehicle needs to be changed every 5,000 to 7,500 miles when using synthetic motor oil.

Subaru Ascent

This article will tell you what oil to use in your Subaru Ascent, as well as what fluids you need to maintain your Subaru Ascent.

Contents

For new Subaru Ascent vehicles, it is recommended to use 0w-20 viscosity, API SN, SP, or ILSAC GF-5, GF-6 engine oil.

Subaru Ascent Motor Oil Capacity

A full synthetic oil type is the best for the Subaru Ascent. The SUV’s 4-cylinder engine holds 4.8 quarts of SAE 0W-20 engine oil.

Subaru Ascent Motor Oil Viscosity

New Subaru Ascent vehicles should use 0w-20, 5w-20 or 5w-30 viscosity engine oil. For vehicles with over 100,000 miles, you should use 10w-30 viscosity oil.

Subaru Ascent Engine Oil Specifications

When selecting oil for your Subaru Ascent, consider API and ILSAC specifications. For new Subaru Ascent vehicles, oil that meets API SN, SN+, SP, and ILSAC GF-5, GF-6 must be used.

When choosing your engine oil, consider the mileage of your Subaru Ascent and the operating conditions of your Subaru Ascent.

Subaru Ascent Engine Oil Reviews & Buying Guide

When selecting engine oil for your Subaru Ascent, consider the mileage of the Subaru Ascent and the condition of the engine. For a new Subaru Ascent and a low mileage vehicle, it is best to use synthetic engine oil.

Synthetic oil for Subaru Ascent

Synthetic oil has a significant impact on Subaru Ascent’s fuel consumption due to its physical and chemical characteristics. Because of its high fluidity and friction properties, friction losses in the Subaru Ascent engine are significantly reduced. This means that more of the energy released in the combustion process will be transferred directly to the wheels. As a result, the gas pedal in the Subaru Ascent becomes more responsive with less fuel consumption.

When using synthetic oil in the Subaru Ascent, there is less friction in the engine and transmission at low temperatures than when using high viscosity oil. This provides improved Subaru Ascent engine starting performance, fuel economy, and lower emissions when the Subaru Ascent is operated in cold cycle mode.

Subaru Ascent 0w-20 Engine Oil

For new Subaru Ascent vehicles with less than 50,000 miles, we recommend using a synthetic 0w-20 viscosity engine oil that meets the API SP, ILSAC GF-6 specification.

Subaru Ascent Engine Oil Review

Engine Oil Type for Subaru Ascent

There are two types of engine oils: conventional oil and synthetic oil. Lately, Subaru Ascent owners choose synthetic motor oil simply because of its quality and good molecular consistency.

Synthetic engine oil for Subaru Ascent has an improved molecular formula, due to which it practically does not oxidize, does not react (for example, with engine oil seals), has an improved viscosity, also practically does not oxidize.

Synthetic oils for the Subaru Ascent have many additives that help increase engine compression as well as reduce fuel consumption. Winter starting the engine is much easier since the oil does not thicken as much at low temperatures.

The only disadvantage of synthetic oil is its high price compared to conventional oil. We recommend using synthetic oil in newer Subaru Ascent models, and conventional motor oil in older Subaru Ascent models.
