Should I perform my first oil change at 1000 miles, or when the manual says?

The 1000 mile oil change is a holdover from days of yore. It falls into the "my grandfather /father (add appropriate generation) said you should always"... Add what ever urban myth was part of the ...

What is the point of changing coolant if it gets constantly replaced?

The logic behind replacing the coolant, rather than just topping it off, is to remove impurities. If the reason you have to add to it is that there is a slow leak somewhere, you may get by with just ...

What is the point of changing coolant if it gets constantly replaced?

You shouldn't be constantly replenishing the coolant - if you are, there's probably something wrong with your car! Modern car cooling systems are designed to be almost maintenance free, so you ...

Should I perform my first oil change at 1000 miles, or when the manual says?

Do what it says in the owner's manual. FWIW the manual said the first oil change from new on my current car was at 18,000 miles, not 1,000. I queried that with the dealer and the reply was "yes, that'...

Why is the ATF Level checked with the engine running?

There are two main things about tranny fluid: Transmission fluid is checked when it's hot (up to running temperature). As the fluid gets up to temperature it expands. If the fluid is cold, it won't ...

How important it is to drain all the oil when doing an oil change?

Old oil isn't poison to your engine or to the new motor oil you are putting in. When you are doing an oil change, whatever old oil is left behind (along with the particulates floating around) will get ...

I believe you just dripped some oil on your exhaust when drained it, don't worry, and your "paranoid" stuff is good - it means you care. Good job Snake! ;)

According to this 2016 Honda Pilot Manual (pages 28, & 146-148), the information display is informing you that your oil has 30% of its life left. After the oil change has been completed, the oil ...

Any truth to the "myth" about changing transmission fluid in older vehicles?

Rotating tires based on time or miles?

In a word: miles. Time has an effect on the tires, but it will deteriorate the rubber all the way around at a given rate. A tire is good for many years (some longer, some shorter). It's the effect of ...

Why is a motorcycle's service interval more frequent than a car?

Service intervals are more of a function of tolerances and MTBF than anything else. There's extensive data available for passenger car longevity, not so much for motorcycles, so car manufacturers ...

How do I tell if I screwed up my oil change?

I think you'll be OK. Drive it around a bit more, and that oil, which sounds like it's on the exhaust pipe, will burn off. Your oil pressure sounds in the normal range - it's usually lower at idle (...

What happens if I use the wrong weight of oil?

Quite likely, nothing… A higher viscosity oil, at the low end, would move a little less freely through the engine when cold. That could result in somewhat higher wear as the engine warms up, but over ...

99 Honda Odyssey had brake fluid flushed 4700 miles (27 months) ago. Does it need to be replaced again?

Brake fluid replacement is not determined by the amount miles on the vehicle, but by the amount of time. That's because it is hygroscopic, which means it absorbs water. It does this through the rubber ...
