After talking recently with the service manager of my local Lex dealer, I am interested in what other 460 owners are using in thier oil changes. The manager I spoke with said that synthetic is mandatory but that 5/30 should be fine with no adverse effects. Now we all know that Mobil 1 comes in that weight, is a high quality product and is quite reasonable to purchase (especially on sale at Costco).

Are there many here who are already using this product rather than the much more costly prescribed oils? What guidance have you received from Lex service people? I am searching for a common sense approach to the issue not an ideological and obsessive one. Thanks!

Lexus did my last change and asked me for my preference (no price difference) - I went with synthetic. I plan to do my own oil changes from now on and will continue with this choice. The price at Costco is dropping - in the Northwest, they sell Castrol's Syntec 5/30 and I noticed the price was $5.66/litre two days ago, a dollar less than a month ago.

In the Philly area (go home team) Costco currently has a coupon for $9 off a six pack of Mobil 5/30. That makes it just about the regular price of $23 or about 3.75 a qt.

Good intel. I'll keep an eye open for the coupon out here... Thanks!

the coupon is in the mail. it should have come a few weeks ago? i already used mine to get 2 cases of 5-30

i don't own the 460 anymore, but you guys sure the spec is 5-30 for the 460 engine? somehow i thought it's 0-20, but i am just playing back from memory.

and personally, i'd just stick with synthetic

Lexus allows both 0w-20 and 5w-20 for the LS460. 30-weight oil is a thing of a pass for lexus as they have switched over to mostly 20 weight. 5w-30 is fine, however i would opt for 5w-20/0w-20 if possible in case they give you a hassle for warranty work later on.

ah ok, that makes sense, coz' i remember when i did my first oil change my friend (master tech) told me different oil would be used

My neighbor's brother has an LS460 and he mentioned he used Pennzoil Platinum 0W20. They also have a 5W20 version to my knowledge.

Lexus dealers use Toyota 0W20 oil made by Mobil 1. You can also find Mobil 1 OW 20 at Wal-Mart...

Thanks, Craig! What is the price there?

The cap says 0w-20 or 5w-20. It's not clear to this non-mechanic is that means it must be synthetic (or not).

Put another way, are those two weights ONLY available in synthetic...if so, then, why doesn't it say "use synthetic oil only" to clearly affirm what they mean?

And if those weights of oil are available as old style dinosaur remains is that OK to use?

those are just weights of the oil, it doesn't mean synthetic or otherwise. but personally i use synthetic all the time

Johnny

Synthetic oils are usually clearly marked on the container. Otherwise they are petroleum based.

Not to be a pest, but again I ask the crux of my question: Are those weights of oil manufactured and sold as refined from old-fashioned dinosaur juice (non synthetic)? No one has answered the question if there is really a choice (dino or synthetic) or if you can ONLY get those approved weights in synthetic.
