There is a wide variety of cooking oils from plant sources such as olive oil, palm oil, soybean oil, canola oil (rapeseed oil), corn oil, peanut oil and other vegetable oils, as well as animal-based oils like butter and lard.
We called a couple of the brake fluid companies and the answer was two to five years is a safe number for an unopened container. Wilwoodâs tech line claims that if the container is sealed, they feel it has an unlimited shelf life, but I would consider five years to be the limit.
You're supposed to change the brake fluid every 2 years or 24K miles. Local dealer charged $78.00 for the job. The transmission fluid change was don't at 39K and cost me $220.00. The original spec called for no fluid changes, but the SA tells me that MB started recommending ONE transmission fluid change at 39K.
