Base oil for internal combustion engine oil

This series of products is a high quality, high flash point, low pour point, anti-coking, anti-carbon, environmental friendly special ester. It has a high solubility of additives, and improves the low temperature, viscosivity and clean dispersion of internal combustion engine oil. Increase the polarity of the oil, improve the oil in the process of high temperature lubrication, and the metal surface has a high affinity, called the track effect, and has an anti-friction effect, improve the service life of the internal combustion engine oil.Can produce a variety of fully synthetic or partially synthetic internal combustion engine oil.

Product Details

Multi-Grade Ester Base Oils for Full-Synthetic and Semi-Synthetic Engine Lubricants

BASOILS Synthetic Ester Base Oil for Engine Oil Formulation is a multi-grade synthetic ester base oil series developed for lubricant manufacturers formulating full-synthetic and semi-synthetic internal combustion engine oils.

The product range includes low-, medium-, high-, and ultra-high-viscosity ester base oil grades. This gives formulators flexibility when designing engine lubricants that require improved low-temperature flow, additive compatibility, ester polarity, metal-surface affinity, and viscosity balance.

Selected grades can be used as a primary base-oil component or as a co-base oil with compatible PAO and mineral base oils. Final grade selection and dosage should be determined according to the target SAE viscosity grade, engine type, additive package, operating temperature, volatility requirements, and finished-oil performance targets.

Grade Selection Guide

Grade GroupAvailable GradesInitial Formulation Direction
Low-Viscosity GradesDA31, DA41, TMP107, TMP108A, TMP108B, TMP108D, PE451Low-temperature engine oil blends, viscosity adjustment, lubricant formulations requiring lower base-oil viscosity
Medium-Viscosity GradesTMP108C, DA51, M80General engine oil formulations requiring balanced viscosity and low-temperature performance
High-Viscosity GradesM100, POE150, J115Higher-viscosity engine oil blends and formulations requiring stronger oil-film support
Ultra-High-Viscosity GradesJ135, J460Specialized high-viscosity lubricant systems and viscosity-building applications

This guide is for initial grade selection only. Final selection should be based on the target SAE grade, base-oil blend design, additive solubility, volatility requirement, low-temperature targets, and finished-engine-oil testing.


FAQ

What is synthetic ester base oil for engine oil?

Synthetic ester base oil is a lubricant base-oil component used in engine oil formulations to support properties such as lubricity, polarity, low-temperature flow, additive solubility, and oil-film retention.

Is this product a finished engine oil?

No. This series consists of ester base oils for lubricant formulation. A finished engine oil requires a complete base-oil blend, additive package, and performance validation.

Can these ester base oils be used in semi-synthetic engine oil?

Yes. Selected grades can be evaluated as co-base oils in semi-synthetic engine oil formulations with compatible mineral oils or PAO. Final miscibility and performance should be tested.

Which grade is suitable for low-temperature engine oil formulations?

Low-viscosity grades such as DA31, DA41, TMP107, TMP108A, TMP108B, TMP108D, and PE451 can be considered where low-temperature flow is a key formulation target. Final selection depends on the required finished-oil viscosity and additive system.

Can the product improve engine oil additive solubility?

Ester base oils can help support additive solubility because of their polarity. The actual effect depends on the specific grade, additive package, blend ratio, and finished-oil formulation.

Can the product be used as a friction modifier?

The ester structure may support lubricity and metal-surface affinity. However, it should be positioned as a base-oil component rather than as a direct replacement for a dedicated friction-modifier additive.
