There's no reason for you to be using a 40 weight oil.

Why so? THanks.
Tolerances... Lets say you want to break a bolt free. There's zero tolerance between those bolts. Using penetrating oil (thin) you may have a chance at breaking it free. Adding heavy oil will never get you inside the tolerances.

Thank you. What oil would you recommend for my honda fit 2000?
My .02 cents... I'm not an engineer. I have nothing to do with the manufacturing of engines. Although I do work for one of the largest diesel engine manufacturers in the world. I see the effort that goes into the engineering. I see the debates between different functions, etc.. When an OEM has a recommendation, it's for good reason. Yes they are seeking value and profit but they have also weighed a few important things.

This page can explain a lot.. Some is easily understood. and some is over the top for me and will need more time with google to self educate. - Effects of Shearing
Best page I've ever found for not going completely off the chemistry deep end. - Oil Viscosity Explained |

Off topic. I used to own a 2008 Civic Si & I love to slap my i-vtec towards redline and I was using mobil1 fully synthetic 5w20 and i recognize that my engine oil decreases for no reason. Apparently, when i switched to redline oil. I saved more gas mileage, more hp and torque as per dyno results and most importantly no decrease of engine oil. |

This helps reinforce and more thoroughly explain how oil functions in three critical ways. In your type of use the Redline oil must have been a better fit.

Awesome. :) Thanks, bud.

I'm stumped at something no one noticed my eyes are acting silly. Did the OP state he had a '00 Fit? But stock Honda recommends 5w-30. Then Honda changed to a synthetic blend 0w-20 all in the name of fuel economy while protection stays the same. Honda also backed a list of older model cars Like 1st gen fit, civic, base RSX, all Accords since 03. only civic si, RSX-S, S2000 stayed 5w-20. If u ever wondered why your mpg was blah, that could be one reason.
