if u just drain and then refill it.. and u have a 98-05 GS then u refill it with 2.5qts from the Lexus standard
Under the front camshaft caps that house the ocv's. It's best to do your timing service at the same time since it needs to be removed to get the caps off.
that may be a hard question because of after market oil coolers I would piur it in till its full
i have a 1999 gs400 but i believe it is the same. look under the front of the car and there is a cover with about 10-12 bolts covering the engine. remove the bolts and you will find the oil filter on the bottom of the engine near the front right tire. hope that will help you. I too, have a 1999 Lexus GS400 and there are about 16 bolts to that cover underneath and I found that there is no need to remove that cover. (PAIN!) You can use oil filters: FRAM PH3614, Havoline T-29, Pennzoil PZ-21, Quaker State QS3614, Valvoline V025. The pan bolt is 14mm. Engine takes 5.5 quarts of oil. (Mrs. Arias☺)
Do it yourself its easy. Put the front of your car on some car ramps, drain the oil, and take the whole pain off, take all the screws out and out comes the pain. Clean it with some kind of cleaner, for example carbuerator cleaner, where the gasket goes, let it dry and install the new gasket.
