Ditto....And besides, the Fumoto is S L O W in draining and only slows up the process. Taking the cover off isn't that big of a deal anyway.....beats what they do at the dealership!(They jusy remove a couple of the screws and then BEND down the cover)

 

I am a fanatic about clean oil. I even buy an extra quart to pour down the oil filler to be sure to get all the dirty oil out. I now use synthetic oil so that even costs an extra few bucks. WHen you park your G35 on a slant, or use ramps you leave a lot of oil in the pan that cant escape out the drain hole as it settles towards the real of the oil pan. If the car is parked level the design of the pan allows nearly all the dirty oil to escape.

just my $.02 worth

 

being that the drain plug IS at the rear of the oil pan (and on a downward angle) I find that partially pulling up on my ramps a great advantage in getting ALL oil out. I also let the car "sit and drip" for quite a while before buttoning her back up.

 

The oil drain plug is at the rear of the sump. Putting the car on ramps will therefore aid in the draining process. If the drain were at the front of the sump, your argument would be valid.

Also, you have to be very careful with the height and incline of the ramps because the car is so low.

Well I changed my oil yesterday, and I was going to install the drain valve. Upon really looking at it, I don't like how much lower to the ground it is compared to the oil pan. Plus the valve screws in too deep into the oil pan, so that at least, a 1/2" of oil would be left in the pan after draining.

I agree that it is a excellent way to obtain mid-stream or occasional oil samples for analyst, but I don't feel comfortable having it installed. One smack of road debris or bottoming out, I feel it would take the brunt of the force and shear off the oil pan.

I have one fumuto valve with spring for sale

Just my .02 cents of opinion, nothing more, nothing less

 

I dont know what yeear your car is but on the 05 the oil drain plug is on the passenger side of the pan towards the rear but not at the rear. If the front of the car is elevated there is enough room for probably close to a cup of old oil that could remain in the pan, depending on elevation..

 

Yes, you're correct. My friend and I tried to do this on his g35 (except insead of driving the front onto ramps, we raised the front and put jackstands under) and we get a lot more oil draining out after we lowered the car to ground level.

I believe the correct way to do it would be to get all four tires off the ground... this way if you're doing an oil change say... every 7k miles, then u can rotate the tires too (sedan) and inspect the differential fluid level and transmission fluid level (6mt models). Note however, if you extend drains past 3750 as stated in the manual, make sure you use a better filter. And I'm not just talking aftermarket, I mean a filter which is larger in diameter or length or or both. Equivalent filters (with same connections and thread) are Amsoil SDF-20 and Amsoil SDF-36. (the original is an SDF 13)

I'm not sure if the SDF-36 will actually fit (due to clearance issues), but if it will, its probably your best bet because you will increase your dirt holding capacity and increase your total oil capacity.

Does anyone know the best way to jack up the rear so jack stands can be thrown under the jack points?
