Oil is oil or is it??

Moving on. Moebius states that the lineup of oils they offer are ether alcohol based. This expression has bugged me for a while, as is doesn´t seems to be the choice of base oils for other commercial products.

Based on my findings (ChatGPT and Google) base oils synthesized from alcohol and esters are expensive an offer a very high quality. Ether is a well known additive for synthetic oils.

Ethers:

- Base Fluid Component: Some synthetic lubricants use polyalkylene glycol (PAG) or polyol ester (POE) bases, which often contain ether linkages. These provide excellent thermal and oxidative stability.

- Low-Temperature Performance: Ethers help maintain fluidity at low temperatures, preventing thickening or gelling in cold environments.

- Lubricity & Compatibility: Certain ethers enhance lubricity and compatibility with seals, reducing wear and extending component life.

Alcohols:

- Precursor in Ester Synthesis: Alcohols, particularly polyols (e.g., pentaerythritol, neopentyl glycol), are used to produce synthetic esters, which are key base stocks in synthetic lubricants.

- Polarity & Solubility: Alcohol-derived esters provide good polarity, allowing better solubility of additives and reducing deposit formation.

- Thermal & Oxidative Stability: Alcohol-based esters resist thermal breakdown and oxidation, which enhances lubricant lifespan.
