Oil was like water!

[Cincinnati Guy]

I checked my oil the other day and when I pulled the stick, the oil was so dang thing it started just dripping off the stick. Its weird I have not even put 1000 miles on it since its last oil change! I smelled it for diesel, and didn't smell anything. My truck dont seem to use or lose oil because its always right in the same spot on the stick. I used the case ih brand oil. Ive never used it in my truck. Hopefully its just that my truck didn't like that oil. I went out and got a fl1995 and 3 gallons of Rotella. Hopefully this dont go thin, if it does it has to be fuel in the oil right?

Also hopefully this was the cause of the ticking. Id go drive it but Ive got another project to finish up. Adjusting the Waste gate and installing the factory turbo heat shields.

What did you put in? 15-40?

 

[Cincinnati Guy]

Yea 15w40.

Might want to check your lift fuel pump to see if the seals have ruptured.

Could it be that in summer 15W40 is not a good choice? I'm noticing the same thing. It's too thin. I thought the mix probably have more of the low than of the thick oils .
I asked the guy in NAPA and he said I can put straight 40 but it's about $16 a gallon. I'm changing the oil today and I'm thinking if I should do a test with the 40.

I wasn't able to smell any diesel fuel in the oil I removed.

You may not be able to smell it if only a little. I have tried straight weight in mine in summer and the pressure is actually lower because of the lack of viscosity improvers in straight weight.

Well since summer is well on it way out I definatly wouldn't change to 40 wieght now

Our summer reaches until November here! We still have 90's at 2:00 PM. I change the oil every 3,000 miles, it takes only two months for me to drive that amount of miles.

How can I check the fuel pump?

 

[lotzagoodstuff]

Pull it off, should be pretty obvious if you have diesel on the wrong side of it.

Mines always been thin with 15w40. Never overfilled or smelled like diesel
