That's probably true, but the 4 bucks worth of brake fluid and 10 bucks worth of coolant isn't going to break the bank. It's cheap peace of mind in my book.
I have no clue know if you have in particular (just quoted one of these comments), but comments like this always make me smile a little due another very commn question: what grade fuel to use. Even when high octane is the recommendation, you typically see people say the lowest without pings...even though if you drive 1,000miles/month, it'll set you back $5. lol
