Is the oil bypass filter physically any different from the regular oil filter? Just curious since they look identical apart from the name stamped on them. I got thinking about it doing my oil change this weekend and figured I would ask. Always love to learn!
 
Hello,

The Volvo D4 oil filters are in fact a little physically different. The bypass filter actually has a smaller opening where it threads on, making it impossible to install the filters incorrectly. Please feel free to give me a call in the office anytime with any other questions (253)839-5213.

Interesting. I hadn’t looked at them close enough to realize that. They seemed identical to me. Good to know! Thanks.

Do the Ranger tugs come with bypass oil filters standard?
 
The Volvo D4 has a bypass filter next to the regular oil filter, both on the port side of the engine.
