Discussion Overview

The discussion revolves around the differences between synthetic oil and two-stroke/cycle oil, including their applications and suitability for various engines and uses. Participants explore the characteristics of these oils and their specific applications in lubrication and performance.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the specificity of "synthetic oil" and its applicability compared to two-stroke oil, indicating a need for clarity on when to use each type.
  • Another participant notes that two-stroke oil is mixed with fuel for lubrication and can be synthetic, emphasizing that oil choice is application-specific.
  • A later reply mentions that synthetic oils can perform better than natural oils in extreme temperatures, but this performance can vary by brand and specific use case.
  • Some participants argue that no single oil is ideal for all applications, highlighting the differences between fuel oil mixes and lubricant oils.
  • It is suggested that while synthetic oils may not always be the superior choice, they can be beneficial for certain needs.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the superiority or universal applicability of synthetic oils versus two-stroke oils, indicating multiple competing views on their uses and effectiveness.

Contextual Notes

The discussion highlights the complexity of oil selection, including factors such as temperature performance, application specificity, and the nature of the oils involved. There are unresolved aspects regarding the definitions and characteristics of different oil types.

What is the difference in oils between "synthetic oil" and "two stroke/cycle oil", bearing in mind I known 2 cycle is for 2 strokes. "Synthetic oil" doesn't seem very specific and I don't know whether to use this instead of 2 cycle for any kind of engine and just for general use. And talking about general use oil for gears, bearings, shafts etc what kind of oil should I use

Any help would be useful

Two stroke oil is added to the fuel to lubricate the engine on the way to being burnt with the fuel.
Two stroke oil can be synthetic.
The oil and any additives used is application specific. Synthetic oils are used when performance beyond that of natural oils is required. There is no one ideal oil for everything.
 
synthetic oil depending on the brand can be used in extreme temperatures where natural oils will freeze or become too viscus to flow through the engine. some brands are made to be penetrating oils as well so a thin film will be in the metal pores even after the oil has settled to the pan but this is not all synthetic oils and natural oil also does this to a lesser degree. as was said above no one oil is universal as in a fuel oil mix vs a lubricant oil which is not burnt off during combustion. synthetic oils are not always the better choice depending on the use but can be for other needs.
