Does your GM Vehicle call for SAE 5w-20? What you should know.
By on Mar 19 2024
Did you know that General Motors recommends dexos1™ 0W-20 viscosity engine oil for applications originally calling for SAE 5W-20? That’s right! Although some engines initially did require (and clearly posted on the engine oil fill cap) that a SAE 5W-20 be used, current testing by GM Powertrain Engineering Department has validated and approved the use of 0W-20 dexos1 as an acceptable substitute and optional top-off and service fill for these vehicles.
Other things you might want to know about dexos1™ engine oil:
- So far 254 SAE 5W-30 products are GM licensed, 186 SAE 0W-20 are licensed and only about 25 SAE 5W-20 oils have been licensed as dexos1™.
- SAE 0W-20 viscosity is used to maximize its contribution to fuel economy improvement.
- Formulated to provide added protection against low speed pre-ignition, LSPI*, which is critical in GM’s small displacement turbocharged engines.
- New additive chemistry to protect turbocharger from harmful deposits.
- Only oils displaying the dexos1™ trademark and a registered trademark logo on the front label meet GM stringent oil requirements.
- Look for the 11 digit GM dexos® license number on the back label for an authorized/approved GM lubricant.

GulfTEC® Full Synthetic dexos1™ Motor Oil exceeds API SP / ILSAC GF-6 requirements for new cars under warranty. Highly recommended for use in gasoline-fueled and flex-fuel passenger cars, light trucks and sport utility vehicles. Fully backward-compatible making it an excellent choice for previous model year GM vehicles.
Low Speed Pre-Ignition (LSPI)* most commonly occurs in smaller displacement engines developed to meet higher fuel economy standards. It is random premature ignition which often occurs under low-speed, high-torque conditions in turbocharged gasoline direct-injected (TGDI) engines and can be more destructive than typical engine knock.
