80w90 gear oil is a popular option for many manual gearboxes, differentials, and transfer cases. Running a high-quality gear fluid in the correct specification not only ensures smooth gear change but is vital for the protection of internal components, plus gear faces and teeth.
If you're in any doubt if an 80w90 gear oil is correct for your car then you'll normally find the correct spec stated in your owner's handbook. If you're still unsure, or you have a unique or modified vehicle, feel free to ask the Opie experts for gear oil advice and recommendations.
