For that car, any oil and filter should work fine.

For the most part, oil is oil. As long as it’s the right weight, they all have to meet certain standards. I don’t think many are exceeding those standards by a lot.

What happens if the weight isn’t correct?

@Finnley
It can lead to increased engine wear if it’s too light, or worse fuel economy if it’s too heavy.

That’s odd. I’ve used 15-40 in all my cars and never noticed a difference in fuel use.

@Finnley
It might be a small change, but heavier oil definitely affects mileage. Manufacturers are moving to lighter oils to meet EPA standards for a reason.

@Finnley
It depends.

Sure, but not all oils meet the same standards. There are different standards.

You didn’t mention the engine. Supertech 5w20 FSHM only meets API SP and ILSAC GF-6A. All three engines require at least ACEA A5, which this oil doesn’t meet. This matters more for the 1.6T and 2.0T engines than the 2.4, but it’s still an issue. The filter is fine though.

@wilison
ACEA is a European standard. I assume Supertech doesn’t bother with European certification since they don’t sell in Europe.

A5/B5 has been around for over 20 years and replaced by A7/B7. C3 is often used for emission devices. Lots of oils meet or exceed the specs needed for these engines. High-mileage oils are often not up to par compared to full-synthetic ones. Ignoring the recommended viscosity, especially for newer engines with VCT/VVT, small tolerances, or engines that don’t see much hard use, isn’t a great idea.

@wilison
The viscosity listed on the oil cap is what should be used. With proper oil and filter changes, the car will likely last long before any oil-related issues.

15

I don’t know much about those filters, but Supertech full synthetic high mileage oil is very good.

16

Fresh oil and filters always work better than used ones.

17

Definitely better than skipping an oil change.

That’s probably the best response so far.

OEM oil filters are cheaper than aftermarket ones, at least for my car (21’ Mazda3).

OEM doesn’t always mean best.
