Oil additives for Diesel

I’ve been instructing the Fundamentals of Machinery Lubrication course for a few years now, and many times the course has been the birthplace of the articles I’ve written. The questions and discussions in the course are very representative of what the average maintenance professional is curious about. Most tend to like the discussions about passenger car and truck oils because they not only affect them at work but also at home. In fact, I use this curiosity to my advantage. If I ever notice a subject is starting to bore an audience, I’ll find a way to incorporate an automotive twist to it. Soon all the ears seem to perk up. This article is no different. I plan to explore the similarities and differences between gasoline and diesel engine oils to appease your curiosity.

In the broadest sense, gas and diesel engine oils have the same anatomy or makeup. They are formulated from the blending of base oils and additives to achieve a set of desired performance characteristics. From this simple definition, we start to diverge when examining the lubricant’s required performance for each engine type.

Emissions and the Catalytic Converter

A catalytic converter is a housing that contains porous metal filler located between the engine and muffler in the exhaust system. Its role is to convert toxic emissions coming from the engine to stable byproducts before they enter the atmosphere. Some of the byproducts of combustion (lead, zinc and phosphorus) can severely cripple the converter’s ability to perform this job. Therein lies the first major difference between the oils. Diesel engine oils have a higher anti-wear (AW) load in the form of zinc dialkyldithiophosphate (ZDDP).Click Here! The catalytic converters in diesel systems are designed to be able to deal with this problem, while the gasoline systems are not. This is one of the main reasons you don’t want to use a diesel engine oil in your gasoline engine. If your automobile was built prior to 1975, there is a good chance it does not have a catalytic converter, and thus the above statements do not apply.

Viscosity

Viscosity is the single most important property of a lubricant. When I am working as a consultant and designing a lubrication program, one of the first steps I take is to calculate required viscosities. Getting the right viscosity is of the utmost importance. The selected viscosity needs to be pumpable at the lowest start-up temperature while still protecting the components at in-service temperatures.

Oil additive for diesel van to strengthen oil seals?

Fiat Ducato 1.9 TD 1994

very much doubt there is such an additive. if seals are leaking they are worn and need changing. a worn engine creating excess Internal gas pressure or a faulty breathing system can also 'push' oil past seals.
oil seal material is designed to work with lubricants and remain flexible to a degree though they do harder over time with age and heat and immersion in oil. this in itself can give rise to 'weeping' or what looks like an oil leak from a seal.
you may find one or two products on market that claim to to so and so eg STP but reality will probably be to change seals.

Can diesel fuel anti gel additive be used for heating oil?

Yes, home heating oil and diesel fuel are almost identical and can be used interchangeably. Home heating oil used in a diesel vehicle is subject to road tax and you can be fined if caught using it to avoid road tax.
