Better off jacking it up TBH. My ramps (supercheap ones) were a complete waste of money. As mentioned, they have a tendency to shoot out from under the car as you drive up them, so i never use them now.

Is it the design? I've never had trouble with mine

[Yowzer 29,062]

If you can get them to grip, and your car isn't too low with too much overhang they're alright. I can't get my Cressida up on mine though, bumper just shoves them away

Cheers guys.

Looks like I'll get my arse into gear and make a set to suit a low car, and not be smooth on the bottom so they don't slip out. 

There were a few reviews on the supercheap and repco ones saying they slip out.

Thanks again.

I generally lay some timber on the ground to make ramps. Height and slope become infinitely adjustable.

They're very steep. I believe you can get extensions to make the angle less, which might help. You can also get grippy things that attach to the bottom of the front edge, but I tried a few things to stop them sliding and have only ever managed to drive a car up them once without them scooting along the garage floor. Polished concrete floors dont help either.

Safe as fuck

Timber is strong in compression.

I don't have to jack my cars up for oil changes..

What I have done with my ramps before is jack the car up and drop it onto the ramps. Easier than stands, and you can drive off them afterwards.

Bugger using bits of firewood though lol. When you said "wood as ramps" I thought you meant planks of wood laid on top of each other. Bits of cut up pallet is mint for that (and awesome for getting jacks under low cars for free)

Wanted to re-use some expensive gear oil with less than 100KM on it.  Was full of glitter.

Tried running it through a funnel on top of a pipe filled with rope.  No luck.
Cut the top off an oil filter and put it in a funnel with a magnet on the bottom, that caught the big chunks but there's fine bronze glitter oozing through the filter. (repco brand)

Aside from tell me that engine oil filters aren't that picky & let through some stuff i wouldn't want in my engine, what else should i strain the oil through?
Doesn't seem to wick uphill and back down into a container through a rope.  Appears too thick for that.

[Yowzer 29,062]

Bin it, buy new oil

Or build a centrifuge

Coffee filters are pretty fine.

[tortron 46,297]

Get it warm and filter it through your rope again

[00quattro00 4,129]

Heard a roll of toilet paper makes a good filter

[mjrstar 2,661]

Along the same line as coffee filter, if you have disposable paint filters they work pretty well. I think I purchased a box of 500 or a thousand for 40 bucks maybe. 

[RUNAMUCK 23,846]

Paint filters must be much bigger holes no? 
Because paint is much thicker than coffee. My recolection was it was a vert slow process getting used motor oil to pass through one. 

[Snorkpipe 302]

Pour it through a loaf of bread, then buy new oil

Haha paint once thinned and ready to pour into your spray gun is not that thick. Well not with my thinning ratio.
