Important common notes

General awareness about proper fluid selection

• Beware that selecting a suitable / proper fluid (oil, coolant, etc.) is vital for the longevity of the mechanical systems which use those fluids!
  • For example, the longevity of the engine, gearbox, etc. is highly dependent on what exact oil type is used.

• Using a high quality fluid from a good manufacturer is one thing, but equally as important is using a properly matching type of fluid.
• However, selecting a proper fluid type can be a rather tricky endeavor, as there can be significant differences among seemingly unimportant specification details.
• For example, the most common misconception regarding oils is that only the viscosity specification is relevant / important.
  • This means choosing an engine oil only by looking if it's 10W-40 or 5W-30 or etc.
• Oil's viscosity is just one of its attributes.
• Oils have many other chemical attributes which are equally as important.

• Generally, the petrochemical industry and technology is so vastly complicated in discerning all the types, standards, classifications, ranges, compositions, ratings, regulations, gradings and whatnot, that it is very hard even for professional petro-chemists to discern it all.
  • This is additionally made worse by several "moot" standards and classifications in that industry (example are API GL-x classifications).
    • In short, the industry has never settled on properly formulated international standards about many material and chemical characteristics of petrochemical products, so there are various country-level or even "industry jargon" standards in use around.
      • For example, API classifications are an old American industry rating which has not yet been replaced by anything better designed and with world-wide consensus.

Choosing proper fluids

• Luckily, ordinary motor vehicle users do not need to dive deep into all those peculiarities of the petrochemical industry.
  • Otherwise, it would have to be a really deep dive indeed!
• As long as a few specific guidelines are being adhered to, an ordinary user can make a proper fluid selection.

Common notes about motor and transmission oils

• Engine and transmission oils can be of mineral composition, semi-synthetic or fully synthetic.
• There is no formal industry standard or classification for this, so generally any oil (for example: "5W-40 ACEA B3" engine oil) can either be mineral, semi-synthetic or fully synthetic. The only way to determine that is to read the description on oil's container, and one of these three should be written in plain English.
• Mineral oils should be avoided, as they are generally too much susceptible to many things and influences, and they loose their chemical and physical virtues relatively quickly during use.
• Fully synthetic oils should be used whenever possible, as they generally provide the most chemical and material virtues (depending on quality) and have the longest longevity.
• Semi synthetic oils are a very "moot" category, as there is no definition of what a "semi" really represents in terms or percentages or so.
  • In other words, an oil which is 95% mineral and only 5% synthetic is also called "semi synthetic", with equal rights for that "name" as an other oil which is 20% mineral and 80% synthetic.
  • This "vagueness" in definition is usually exploited in the industry.
  • With semi-synthetic oils, the only rough estimation of what percentage of a semi synthetic oil is really synthetic, is to compare its price with its competition.
    • Higher price should mean more synthetic compounds in it.
  • This is why only a fully synthetic oil is a "safe bet".

• It was written earlier that viscosity figures ("xW-y") of oil are not the only important parameters.
• With engine oils, equally important characteristics is the exact "ACEA" category of the engine or the exact vehicle manufacturer's standard which the oil needs to conform to.
  • Either the ACEA classification or vehicle manufacturer's own classification will be specified for required engine oil in vehicle's owner's manual.
    • Examples: ACEA B3, ACEA C4, Mercedes-Benz 229.3, Renault RN0710, Volkswagen 505.00, etc.
• So, to properly choose a suitable engine oil, you need to watch out for three important parameters:
  1. Suitable viscosity (example: 5W-40);
  2. Suitable chemical characteristic classification (example: ACEA B3, Renault RN0710, etc.);
  3. After you find engine oils on offer which match the first two criteria, it's then your own choice to choose a mineral, semi synthetic or fully synthetic oil among them.

• With transmission oils (for the gearbox, transfer box and the differential), the other very important parameter (except the viscosity figures) is their API chemical classification.
• Using a transmission oil of wrong API classification can kill the gears in your transmission!
• So, if the vehicle manufacturer has stated to use API GL-4 oil, make your best effort to adhere to that!
• The difficult part here is that API classifications are quite old and they have been poorly defined from technological viewpoint, so many oil manufacturers now produced "combined" or "enhanced" transmission oils which "exceed" the requirements of these classifications.
• The most common example is a transmission oil which is classified as "API GL-4/5" (non standard manufacturer's "classification").
  • This is quite absurd, as API GL-4 and API GL-5 classifications are by definition totally incompatible!
• The other common example is a "classification" called "API GL-4+" which does not exist in any official books.

• In summary, when choosing transmission oils, after selecting a suitable viscosity, make sure to select an exactly matching API classification.
  • Try to avoid any "enhanced" or "combined" classifications like "API GL-4+" or "API GL-4/5" etc.
    • In other words, if it says to use API GL-4, use only that one!
• The problem is that proper API GL-4 oils (which Jimnys use for the gearbox and the transfer box) are becoming hard to find these days (as Jimnys were designed in the 20th century you know).
• One of tried and recommended API GL-4 transmission oils Ravenol TSG.

• Air filter, oil filter and fuel filter for diesel Jimnys are different than for petrol Jimnys.
• Most DDiS Jimnys with 48 kW engine have the lever shifted transfer box, while the last production examples from 2005 have the push-button shifted transfer box. Hence two specifications in the above table.
• The user manual strongly warns against using engine oils with 5W-30 viscosity, as engine damage is promised in that case.
