Did my first oil change on the ISF and found small (about half a mm in size and smaller) aluminium flecks in the filter and in the bottom of the drain pan after I emptied the drain pan back into a storage container, defiantly aluminium they were not attracted to a strong magnet the drain pan was clean to start with. The car has been serviced by Lexus every time and has only 78000kms the motor is very quiet, I used 1 1/2 litres of oil in 10000 kms, I will drop the oil in 2000kms and have another look never seen this before, one theory is I had it on ramps the oil was very hot and I let it drain completely, not what Lexus would do on a level hoist I hope it was residue aluminium that had never been drained out as there was more in the drain pan than the filter as the car was tilted at a angle to get all the oil out, maybe I'm overreacting as there wasn't that much anyone seen anything similar?? I will send a sample and get it tested cheers.

That can't be good. I would pull a sample and test it ASAP with someone reputable (NOT Blackstone). I do my oil changes on ramps and let it drain for over 30 minutes - never a flake of metal in the oil/filter.

What kind of mods are you running, any forced induction?

Also, please use some more punctuation. Huge run-on sentences are difficult to read - make it easy for us to help you.

I've got three Lexus V8 cars and none of them use anywhere near that amount of oil. Aluminum in the oil is probably coming from the main or rod bearings. I would certainly find out what is going on before something permanent happens.

Drove 3500 miles to Houston, TX and back to CA in our LS 430 much of it at over 90 MPH. Car used about 1 cup of oil.

how on earth do you measure a "cup" of oil??

Not hard to convert. 8 ounces equal one cup or 1/4 of a quart. 4 cups of oil equal one quart or 32 ounces.
Calculating a quarter of a cup is not to hard and you can use the cars oil dip stick to get fairly close. The dip stick is calibrated and usually measures quarts. One quarter of a one quart calibration equals one cup. Not rocket science.

I've frequently wondered why many of you have a difficult time changing the F's transmission fluid. Changing it is as simple as draining and filling. Measure what comes out, then add an equal amount back in, plus one or two cups (that is 8 to 16 ounces). Then follow the approved checking procedure. By the way, drain the pan, then replace that oil. Drain the other five quarts through the transmission cooler lines and replace an equal amount.

I read a lot about these 8 speed transmissions not operating properly when a half a quart low, but haven't read anything about a problem with one overfilled by 8 ounces.

Probably because the simplest part most folks skip when they do dabble in it, and that's that the fluid temps have to be just right and setting the level isn't easy. Its not as cut and dry as it seems

Cups, gearboxes, punctuation, road trips thanks for the info but I still think my theory is right, had a look at some other forums and the amount of flecks of aluminium is small. So I will go on a road trip (hope I don't get a puncture) and my gearbox is all right and have a cup of coffee,
