Customer Questions & Answers

Question:
What is Opti-Lube Summer+ Cetane Booster Diesel Additive used for?
Answer: Opti-Lube Summer+ Cetane Booster is designed to improve diesel fuel performance by increasing the cetane rating, which enhances combustion efficiency. This additive reduces engine knocking, promotes smoother operation, and improves fuel economy. For instance, using it during long trips or high-load conditions can result in noticeably better engine performance and reduced emissions. -
Question:
How does cetane booster benefit my diesel engine's performance?
Answer: By increasing the cetane level in diesel fuel, Cetane Boosters like Opti-Lube Summer+ stimulate quicker and more complete combustion. This results in improved power, lower emissions, and smoother engine operation. If you frequently drive in heavy traffic or under load, this booster can significantly reduce strain on your engine and enhance longevity. -
Question:
Can I use Opti-Lube Summer+ in all types of diesel engines?
Answer: Yes, Opti-Lube Summer+ is compatible with all diesel engines, including those in trucks, cars, and heavy machinery. Its formulation is safe for both modern and older engines. Regular use in various scenarios, such as towing or in cold conditions, can prevent issues like hard starting and enhance overall reliability. -
Question:
What are the ingredients in Opti-Lube Summer+ Cetane Booster?
Answer: Opti-Lube Summer+ contains a proprietary blend of cetane improvers, lubricity additives, and detergents that enhance fuel performance while protecting the engine. By using additives that target different aspects of diesel fuel, such as cleanliness and lubrication, you can ensure optimal performance and maintenance of your vehicle’s engine. -
Question:
How much Opti-Lube Summer+ should I use per tank of diesel?
Answer: The recommended dosage of Opti-Lube Summer+ is typically 1 ounce per 3 gallons of diesel fuel. This means that one 8 oz bottle can treat up to 24 gallons of fuel. This precise measurement allows for accurate and effective enhancement of your diesel without over-application, ensuring you get the best results for engine performance. -
Question:
What are the advantages of using a cetane booster during summer?
Answer: Using a cetane booster like Opti-Lube Summer+ in summer months can counteract energy loss due to high temperatures affecting fuel quality. The booster improves combustion, which is especially beneficial during peak driving periods. This ensures you experience improved engine responsiveness and lower emissions while enjoying your summer drives. -
Question:
Will using Opti-Lube Summer+ affect my vehicle’s emissions?
Answer: Absolutely! Using Opti-Lube Summer+ can lead to lower emissions as the improved combustion efficiency reduces soot and smoke produced during the combustion process.
