Great deal on diesel engine oil. Looks to be really good and have great specs. Going to give a try on my diesel. Production date of November 2024 and Best Before of November 2029. Would just suggest anyone using to shake the bottle to remix additives that may have settled to the bottom. 10/10 would recommend.
