There are many general types of bacteria used as probiotics (two common ones are Lactobacillus and Bifidobacterium), and many different species as well as strains within species. They have different physiological effectsâand thus possibly different health benefits (as well as possible risks). Some yeasts, such as Saccharmyces, can also act as probiotics. Probiotic products may contain a single strain or many strains, and the number of organisms in a daily dose can range from 1 billion to more than 250 billion.
wikiHow to Change Transmission Fluid. Transmission fluid needs to be changed from time to time in order to extend the life of the transmission, usually every 30,000â60,000 miles (48,000â97,000 km) (sometimes more â check your owner's manual for service intervals).
Another problem is that people often use the wrong fluid when they change it. This even happens at shops, trust me. Often times transmissions, even by the same manufacturer, will use different fluid and the wrong one can cause premature failure.Sometimes people use what is cheap, which can be a problem for the same reason.any mechanics believe, perhaps correctly, that if you wait too long (mileage, not color) you should not change the fluid because it could cause transmission failure prematurely; whereas if you had changed it regularly all along it would be ok. People differ on what that mileage might be, but let's say it's 100k miles.
