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.
I have a 2005 Honda Element. The owners manual states the brake fluid should be replaced every 3 years. When I asked the dealer to replace the brake fluid, they said it was going to cost $190. I told them last time they did it, it was only $27.They said it was expensive because they were going to hook it up to a sort of dialysis machine to flush it out.The owners manual doesn't say anything about this.hen you replace brake fluid you are flushing the system. The way you do it, all old break fluid will be removed and new fluid in its place. You should do this as your owner's manual prescribes. I believe normal intervals are either two or three years as your manual says.
