Material comparison at 20 °C
Resistance overview
PETG shows very good resistance (A) to Motor Oil at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.
Application context
Motor Oil is commonly encountered in automotive and fuel storage and transfer. PETG (Polyethylene terephthalate glycol (co-polyester)) is a thermoplastic typically used for tanks, piping, containers and liners. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
PETG can be used with confidence for Motor Oil containment and handling. The A rating indicates that the material shows no significant change in weight, dimensions, or mechanical properties after prolonged contact under test conditions. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.
Did you know?
Temperature is often the deciding factor when selecting materials for Motor Oil: even materials rated A at 20 °C may lose performance at elevated temperatures.

About PETG
PETG is a co-polyester for clear containers. Strong acids and alkalis and most organic solvents attack it.

A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
About this data
The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.
A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
