What is the difference between GF-5 and GF-6 engine oils?
2 Answers
The difference between GF-5 and GF-6 engine oils is that the GF-6 specification includes numerous improvements, such as: 1. Maintenance: Fuel economy and fuel economy maintenance. 2. Durability: Engine durability. 3. Protection: Wear protection during idle-stop conditions. 4. Minimization: Minimization of low-speed pre-ignition. 5. Reduction: Reduction in oil aeration and engine oil air entrainment. 6. Decrease: Decrease in turbocharger deposits. Additional relevant information includes: 1. Fuel economy: Building on the SP standard, GF-6 imposes higher requirements on the fuel economy of engine oils, which can lead to lower fuel consumption for the engine. 2. GF-5 phase-out: GF-5 certification will be discontinued starting May 1, 2021. The performance of GF-1 to GF-5 oils will be replaced by GF-6A oils.
I believe the main difference between GF-5 and GF-6 lies in the comprehensive upgrades GF-6 has made for modern engines. For example, GF-6 has significantly improved fuel economy, meaning your car will run more efficiently, especially for those small-displacement engines with turbochargers. It also reduces the risk of something called low-speed pre-ignition, which often causes knocking damage in older engines. Overall, GF-6 offers better cleaning performance, preventing sludge and deposit buildup, making the engine more durable. Personally, I think if you drive a car made after 2017, prioritizing GF-6 can save you a lot of trouble. It's a new standard introduced in 2020, with upgrades designed to keep up with technological advancements, making driving quieter and smoother. In short, these improvements make GF-6 the better choice.
