Oil??
I'm drowning in online opinions and various website recommendations...
I have an 02 rx300...can a knowledgable lexus owner (who has this car) tell me what engine oil I should be using? My local corner guy last time used what i think was straight 10w-30, which is printed on my oil cap under the hood.
Seems that isn't what most are using now? Can I switch to synthetic? Need oil changed today. I live in TX and car has 103K on it.
Help! Thanks!!

I'm surprised that your cap indicates 10W-30...mine, I believe, says 5W-30. The only difference is that 5W is easier to start/better flow properties when cold, which I doubt applies to you in TX. Either would work. I would use 5W b/c that offers all the protection of 10W-30 w/ better flow at cold temps. (of course, some will argue viscosity modifiers will degrade an oil over time, whatever, at 100 CST operating temp. = virtually identical). I switched to syn. in wife's car at 95K and no problems. I don't like how hot the engine compartment seems and w/ the sludging issues, I sleep better at night w/ "extra" protection (although PYB is pretty good, as others, for dino oil). I use Valvoline Synpower, but will be trying Ultra.
I'll be curious what LexMex says, I just found LubroMoly Engine Flush and will use it soon...on his recommendation in the DIY forum.

My label and owners manual recommend 5W-30 for my '99. I got it with 110+K miles, I use Mobil 1 5W-30 exclusively, and it doesn't use a drop between changes. If I saw significant oil usage, I would probably switch back to non-synthetic.
Funny I have a '99 RX300 with 104k. Switch to synthetic Mobil 1 0w30. Car started to burn oil after my second oil change with this. I switch to conventional oil for Auto-RX. Worked well still burned some oil after with conventional. Then I switch back to the 0w30, the oil burning has stopped weird but true.
If you ask LEXMEX on here, he is using 0w-20. But I would honestly recommend nothing higher than 5w with these motors. I am currently using 5w-20 valvoline synthetic w/ a K&N Filter. That is what i recommend and i would stick with it. There is no way the cap could say 10w-30 unless maybe it has been replaced. But I thought they were all 5w-30. But check your manual if you want to go by the books on this one.
