| Hello guys got a 1952 CA that i am trying to get ready for spring! It has been completely drained of fluids when i bought it and i found that the oil filter had 15/40 written on it i assumed it meant 15w40 was used is this a good oil weight to put in the tractor or is it to heavy? Also is universal tractor fluid good for the hydraulic system or something else? i appreciate any answer! |

The old manuals will say 30wt, but I have been running 15w40 for years without a problem. My only caveat is that I don't use the tractor in the winter. ------------- 1951 B |

15w40 or 10w30 oil is fine.. The 15 or 10 is basically the COLD viscosity, so that is good for winter startup.... Original was 20 wt winter and 30 wt summer. Universal tractor fluid is great for the trans / bevel gear / hydraulics... Dont forget the final drive oil pans inside the wheel rim.. you will have to remove them to clean and reinstall..... Takes about a quart of 80-90 gear lube in each.. ------------- Like them all, but love the "B"s. |

They probably used the 15w40 because it was STANDARD with the larger Diesel tractors on their farm.... Thats fine, but normally 10w 30 would be your choice. ------------- Like them all, but love the "B"s. |

| I use 15-40 in my WD45. Works great. If you do a lot of cold starts in winter then go to 5-40 synthetic for easier startup. |

If I were planning to work my Model C hard in the summer I would run 15W-40, however, I don't ever work it hard so I run 10W-30 and if I were using it in the winter I would use 5W-30 |

| keep in mind that the oils of today are far superior to what they were in 1952, so probably most anything will be fine |

O GOODIE, AN OIL THREAD!!🎉🎉 I’ll get some popcorn. ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |

What brand of popcorn? What oil did you use on it?

Definitely butter. Any brand of popcorn that floats your boat. ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |

Use NON DETERGENT butter, not they synthetic "Margarine" or Vegatable-based butter... ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |

Where does oil WEIGHT come from? When referring to 10W-30, W is for WINTER. Not WEIGHT. Motor oil weighs 8.35 pounds per gallon and has nothing to do with viscosity. The general reference is VISCOSITY. |

Just like "condenser" rather than capacitor of which it really is. So many years have transpired it's part of the jargon. Same thing with "Band-Aid".
For many years we ran straight SAE 20W oil in the colder months, and SAE 30W in the warmer months. Straight 30W oil in the Detroit Diesels all year round with engine preheaters installed. Still have a barrel of each in the shop. ------------- A career built on repairing and improving engineering design deficiencies, shortcomings, and failures over 50 years now. |

| Never knew the"W" stood for winter. So 50W is winter oil??? |

Oil viscosity has always been referred to as WEIGHT... Google "20 weight oil" and you will get PAGES of hits.... If you have ONE NUMBER like 20W , 30W, 50W ... that is called 50 WEIGHT oil and has a viscosity THICKER than 40w or 30w.. ... If you have TWO numbers like 10W 30 ..(multi- viscosity)... the W is the WINTER RATING (10 weight) and the second number is the SUMMER RATING ( 30 wt) ................ In reality it is VISCOSITY, but has been called WEIGHT for a hundred years. and referring to it as "50 weight" is a lot easier to remember than " 210 centistokes @40 degree C"..  ----------------------- Internet..............When it comes to determining and choosing an oil weight, none of it involves weight as we commonly think of it—there are no weight scales involved in weighing https://www.thedrive.com/reviews/27713/best-motor-oils" rel="nofollow - oil . Instead, in this circumstance, weight refers to the oil's viscosity, which is a fluid's resistance to flow. Generally speaking, the higher the viscosity, the slower it'll flow, the lower the viscosity, the faster it'll flow. https://www.thedrive.com/cars-101/36938/synthetic-vs-conventional-oil" rel="nofollow - Oil weight is a critical detail of keeping your engine running as efficiently and reliably as possible, and the way it's identified is a mixture of two rating variables. Let's dive into what those two variables are, why they're important, and why someone might consider deviating from their car's recommended rating for their next https://www.thedrive.com/maintenance-repair/29572/how-to-change-oil" rel="nofollow - oil change . ------------- Like them all, but love the "B"s. |
