Can You Use A Car Oil Filter in a Lawn Mower?

Can You Use A Car Oil Filter in a Lawn Mower

Lawnmower engines differ from each other in terms of power, size, and other configurations. This necessitates installing different oil filters for specific engines. 

Also, a significant number of lawn mower owners often make the mistake of interchanging between lawn mower oil filters and car oil filters. However, they’re not the same.

Lawnmowers do an abusive job of removing grass or weeds from the lawn. Hence, the oil filter is specially designed to prevent grass clippings or other large debris from entering the system. 

On the other hand, car oil filters are mainly intended to keep the engine oil protected from small impurities and particles. 

That means when you use a car oil filter instead of a lawn mower oil filter, the filter will be blocked due to the accumulation of grass clippings and other large debris.  

In addition, there are some other differences that raise the question of whether fitting a car filter to your lawn mower is at all logical.

As a professional landscaper, you might rely heavily on your equipment’s performance. In this aspect, the Stens Kohler 52 050 02-S Engine Oil Filter always shines. 

This oil filter is likely an authentic Kohler part and seems to be compatible with most late model Kohler small engines, including the slightly shorter black version. 

Many people have asked if it will fit their lawn mower, and the answer is yes. The only distinction between this filter and the black one sold by Kohler is the length, resulting in a slightly larger capacity and potentially a longer filtering lifespan. 

As a result, a slightly greater amount of oil may need to be utilized during application. In terms of compatibility, as long as there is sufficient physical space in your Kohler-powered mower for the yellow filter, you can use it regardless of whether your equipment originally came with the black filter. 

However, on the other hand, if you replace your filter annually or after each season of use and your equipment is only lightly or moderately used, using the black filter should be sufficient. 

What we liked;

  • High-quality filtration
  • Easy installation
  • Precise engineering 
  • Compatible with multiple models
  • Affordable price

What we didn’t like:

  • The filter housing may crack or develop leaks over time
