# Dataoil compared: GTL ester vs same-price full-synthetic oils

> Corresponding page: https://laolichem.com/en/compare.html

**How Dataoil compares with other full-synthetics at the same price:** three core differences — base-oil route (the 9000 series uses GTL ester base oil), additive package (core additives from Afton), and test transparency (in-house lab full-item testing + published CNAS third-party report numbers). Competitors are anonymized as "same-price mainstream brands (averaged)" — no brand is named.

## Table 1: Dataoil vs same-price mainstream brands (averaged)

| Dimension | Dataoil | Same-price mainstream (averaged) |
|---|---|---|
| Base oil | 9000 series: GTL ester; other series: top-tier synthetic base oils | Mineral / synthetic-blend / conventional full-synthetic (PAO etc.), varies by brand |
| Additive system | Core additives from Afton; formulas verified by bench testing and on-road validation | Generic commercial packages, usually undisclosed |
| Test transparency | In-house lab intake + dispatch testing, batch samples traceable, key batches to CNAS labs, report numbers published (TBD) | Limited publicly verifiable third-party data |
| Channels | Direct sales on Tmall/JD/Douyin/Pinduoduo, same product same price | Mixed distribution + e-commerce, prices vary by channel |
| Price band | Direct e-commerce pricing, varies with promos (TBD) | Same band |

Base oil sets the ceiling; additives decide how much of it you get; transparency decides how much the data is worth. At the same price, compare what you get — not who's cheaper.

## Table 2: 9000 series (GTL ester) vs conventional PAO full-synthetic

| Dimension | 9000 series (GTL ester) | Conventional PAO full-synthetic |
|---|---|---|
| Process | Gas-To-Liquids: natural gas via Fischer-Tropsch into high-purity hydrocarbons, then esterified | PAO (polyalphaolefin), petroleum-derived, common route |
| Molecular structure | Polar ester molecules, better surface adhesion | Non-polar molecules, good chemical stability |
| Cold-start protection | Esters generally hold film better in the cold | Good cold fluidity; depends on formulation |
| High-load film | Stronger film, suited to high-load high-RPM duty | Good film strength, sufficient for commuting |
| Long-term oxidation | Generally better oxidation stability, longer intervals possible | Depends on grade and additive package |
| Price positioning | Higher (premium base-oil route) | Mainstream band, better value |

**How to choose:** both are synthetic base oils. GTL ester holds relative advantages in film adhesion and oxidation stability at a higher price. High-load, long-interval vehicles suit the 9000 series; for daily commuting a conventional PAO full-synthetic is sufficient — no need to pay for performance you won't use.

## How to read comparisons

1. Compare base oil first. 2. Then additive disclosure. 3. Check whether tests can be re-verified (published report numbers, retained samples). Prices follow live store pricing.
