Re: What engine oil do I use for a Lexus rx300 1998
Castrol 5W30 Synthetic Blend. Do not use full Synthetic, always use synthetic Blend, Full synthetic may not be compatible with engine seals and could result in oil leakage

There are no known issues with any LEXUS manufactured after '02 that would cause this issue by default. If you are burning oil, and its not leaking out, then one of two things is happening.
1. Its getting into your coolant system.
(in this case, check your coolant system for a oil layer. TO FIX THIS you mill have to replace the block / i.e. get a new engine if you want it to last.)
2. Its getting into your valve chamber and burning with the fuel.
(in this case, a gap has formed within the valve system letting in oil and can be identified by white smoke from the exhaust. TO FIX THIS you must replace head gasket and rings)

1st check quality oil and filter, if oil and filter is good, then remove engine oil pan , clean oil pump strainer, instal oil pan , add new oil and check.
if have oil on spark plug inside of cylinder, you need to overhaul the engine, if oil is over the spark plug ,change the valve cover gasket
drain that oil! then flash the engine using the flashing oil! if the problem still persist then that engine must be mixing oil and water through the cylinder head gasket!
getting harder to lexus and toyota to take care of this problem. I have repaired many of them when i worked for lexus. I would car the 1-800 num. for leaxus support.
