ebinmaine 67,421 #1 Posted October 4, 2023 I've been meaning to drop the engine oil outta my 1974 C160-8 .... for awhile. I did not take a picture. Partially because I don't want pictorious proofage. But really... it's a black drain pan.... with black oil. 1 2 4 Share this post Link to post Share on other sites
CCW 1,293 #2 Posted October 4, 2023 I believe that's the color of oil when it comes out of the ground so it should still be good. 1 3 1 Share this post Link to post Share on other sites

JoeM 7,873 #4 Posted October 4, 2023 Remember EB there ain't no filtration on those old K's, that oil is going to be pretty dark by nature of the beast, that means the oil is cleaning up after it's self. 2 Share this post Link to post Share on other sites

That's definitely a good thing. I suppose probably I should get an hour meter on this machine. 2 Share this post Link to post Share on other sites

That may or may not be a good thing because the crud is constantly moving thru the engine causing wear. The only good answer is to drain the oil often and do it immediately after shutting down before solids settle out. An hour meter can be useful but it can't tell you the the number of starts, idle hours, and hard use hours. My thought is take a good guestimate that fits your use over time and go with that. 1 1 Share this post Link to post Share on other sites

I have a "spare" one that you can have. I've never looked at how these work - do they just measure how long the key is on and there is power? Or do they detect the engine running? 2 Share this post Link to post Share on other sites
rmaynard 15,434 #9 Posted October 4, 2023 I was very bad about changing the oil in my wife's car when we were first married. Her father used to pull the dipstick on her VW Beetle, see that the oil was black, and ask when was the last time I changed it. So I started using STP brand motor oil. It came out of the can black, so that ended the discussion. 2 4 Share this post Link to post Share on other sites

Go ahead and throw that in the pile of Bear Parts if you would. On my older C Series from the '70s they detect "Key On." Not sure about the later models... 2 Share this post Link to post Share on other sites

Some power through the oil pressure sensor but most are on the A or I post of the ignition switch - key on, meter on. 1 1 Share this post Link to post Share on other sites
