Can the Buick GL8 use 92-octane gasoline?
1 Answers
The Buick GL8 comes in two models: 2.5L and 2.0L. The Buick GL8 2.5L can use 92-octane gasoline, as the vehicle's manual recommends using 92-octane or higher-quality unleaded gasoline. However, the Buick GL8 2.0L is better suited for 95-octane or higher gasoline for optimal engine performance. Below is additional information: Replacement Cycle: Typically, manual transmission fluid should be replaced every 40,000 kilometers or 2 years, while automatic transmission fluid should be replaced every 60,000 kilometers or 3 years. Precautions: You can determine whether the gear oil needs replacement by observing the feel of daily gear shifting. Generally, replacing gear oil within 20,000 kilometers poses no issues. Beyond 20,000 kilometers, pay attention—if gear shifting remains smooth and transmission noise changes little, you can continue driving with confidence. However, if gear shifting becomes noticeably rougher and less smooth than before, or if transmission noise increases significantly after 100 kilometers, the gear oil must be replaced promptly, regardless of whether the mileage is 30,000 or 40,000 kilometers. Otherwise, it will exacerbate gear friction in the transmission, leading to premature major repairs. Replacing gear oil too frequently results in unnecessary waste, so timing is crucial.
