1/6 to a decimal = .166666667

Does that round off to 17% ?

It depends how accurate you want to be. 16.67% is just as valid.

i agree with mad jew, it depends on how accurate you want to be. i'd be comfortable with 16.7% myself. out of curiosity, why do you ask?

the best way to calculate 16.6666% of something, if that's what you're doing, is simply to divide by six. round your final answer if you have to. good luck. still a bit

Six? Must be quarts. Of oil.

iMeowbot is correct; although I find it kind of spooky that he knows so easily.

I wanted to know the exact viscosity of 1 quart of Valvoline Synpower 5W-40 mixed with 5 quarts of Valvoline Maxlife 10W-30. As it turns out, it's exactly what I'm looking for.

Has anyone else noticed that MACDRIVE makes the most random threads?

You just made my day, hahaha...

Pardon my asking, but why do you need to know the exact viscosity of the two? Are you trying to calculate whether or not it will destroy your engine if you overfill on oil?

Good luck on that 7th grade math test!

I'm glad it got cleared up for you MACDRIVE. I can't imagine accuracy would be all that necessary for your purposes with the oil.

ugh, my sixth grade math teacher made me memorize fraction-to-decimal equivalents for fractions with denominators from 1-12. it comes in handy sometimes, but it does bring bad memories from my youth.

Well given that the precision of the answer will be at least an order of magnitude greater than the precision of the measurement of the two lots being mixed (you're looking at 1 - 2% of the nominal 'quart' being left in the container & wasted because it's viscous and takes a long time to completely drain...) so you don't know within that margin of error exactly how much oil you have of each type.

Soooo... it doesn't matter a whit where you choose to round it. 17% would do...

If you round to the nearest decimal, yes.

It could also round to 20. Or 15. It depends on how much accuracy you want in your rounding.

What do you mean by random threads?

Those numbers are from the oil company's product data sheets of which I enter into the online viscosity calculator for the final viscosity.

Yes I know I'm lacking math skills.

Thank you Hot Jew Babe!

Yeah, next time I'll know to just move the decimal over two places.

devilot, I didn't know about those special image tags, but now I do.

Hi MrSmith I'll have to wait until it's daylight outside to snap a photo, but it looks very similar to this one in bronze mist metallic. Click to enlarge image.

Nice. Looks a bit like a Jag to me. Obviously I'm no expert.

Haha, well yes, I kind of got that I'm wondering what you intend to use the final viscosity value for. Are you calculating the final viscosity just for the hell of it, or do you have a greater purpose in mind?
