Understanding and Solving the Bobcat Making Oil Issue
type: item
date: 2026-08-08T06:10:00+00:00
description: The issue of a Bobcat machine "making oil" is a common yet concerning problem in the heavy equipment world. When this happens, it means that the machine’s engine is somehow contaminating the oil with diesel fuel or other fluids. This can lead to severe damage to the engine and other critical components, making it essential for operators to address the issue as quickly as possible. In this article, we’ll explore the causes of this problem, common solutions, and how operators can prevent such issues from escalating.What Does "Making Oil" Mean?In simple terms, when a Bobcat (or any other diesel engine machine) is said to be "making oil," it usually means that the engine is allowing diesel fuel to enter the oil system. This causes the oil to become diluted with fuel, which can dramatically reduce the oil’s lubricating properties. Over time, this can lead to increased wear, engine damage, and even complete failure if not addressed promptly.In addition to diesel fuel, coolant can sometimes mix with the oil, leading to a similar issue. While coolant mixing with oil is often a result of a head gasket failure or a cracked engine block, fuel dilution is usually related to the engine’s fuel injection system, particularly with older or worn-out components.Common Causes of Fuel Contamination in Bobcat MachinesSeveral factors can contribute to fuel contamination in Bobcat machines. Here are some of the most common causes:Worn Fuel Injectors: One of the most common reasons for fuel dilution in the oil is worn or malfunctioning fuel injectors. Fuel injectors are responsible for atomizing the fuel into a fine mist that mixes with air in the combustion chamber. If the injectors are worn out or malfunctioning, they may deliver too much fuel, which doesn’t burn efficiently. This excess fuel then escapes into the crankcase, where it mixes with the engine oil.Solution: If the injectors are the problem, replacing them with new or refurbished ones is typically the solution. Additionally, c…

description: Honestly, in the Chinese equipment market, you don’t need to worry too much about the ID plate, the engine serial number, or the frame stamping.The reason is simple: to deal with EPA inspections, most machines have those original identifiers covered or removed.What usually happens is this:The selling company buys a complete new set of matching information — the ID plate, the engine serial number, and the frame number — and installs them on the equipment you’re buying.That “new” information is copied from another machine.Everything is done for EPA compliance.My job is to make sure the machine you receive is the same machine you paid for.But I can’t guarantee that the ID plate, engine number, or frame stamping will look exactly the same as when you first saw the machine.Some people care a lot about this.If you’re one of them, that’s fine — you can choose a machine with all original documentation and identifiers intact.Just understand that those machines usually cost more than 20 percent extra.Because of cultural differences, many customers actually want cheaper machines and don’t really care much about the paperwork.As long as the machine runs well and needs very few replacement parts, they’re happy.But they feel awkward saying that directly.And when they don’t say it clearly, it creates misunderstandings when I introduce sellers or machines to them.Chinese customers are usually much more direct.They’ll tell me straight up:“I’m buying this for my company. I need a kickback. I don’t want the best machine — I just need one that works.”Once they say that, I know exactly what the priority is.Almost every overseas customer I’ve met tells me they care deeply about hours and machine condition.But in the end, they all choose a reasonable price, acceptable performance, and a good-looking machine.In other words, they choose balance.When it comes time to actually buy, almost nobody truly cares whether the machine is completely original.So, my friends, you can just tell me honest…

Which “Largest” Excavator Market Is Right for You?
