Hey all...I got a complimentary oil change on my GS today. Normally, I change the oil myself, but it's been too damn hot and smoky here, and I didn't feel like doing it this time around, so I called my GM buddy and he said they'd handle it.

I was very surprised to find out from the service advisor that all Lexus oil changes are full synthetic (I have never heard that before). ALL of them at that dealership are full synthetic, they don't even use dino anymore. I was even more surprised to read on my printout that they used 0W-20 when the manual clearly says 5W-30.

Has anybody else heard of this? And can some members in the know explain the differences between those two oils?

I just googled it, basically its not a big deal, but next time just get 5W30 in it.

****, at Lexus of Annapolis they use Citgo brand oil for your $95 oil change. This is why I have a friend at Jiffy lube that uses full sythetic Penzoil and it only cost me $28 !!

According to Mobil 1, if you want to use a high efficiency oil, then you should substitute 5W-30 with 0W-30. Not 0W-20.

EXACTLY. That's why I couldn't understand the use of 0W-20. I thought someone else might know something that I did not.

I am going to call the service advisor and I'll see what he says.

Factory recommends using 5w20 now and not the 5w30... TSB EG006-06

Coolpop

Good call. That's exactly what the service advisor told me, and he seemed pretty knowledgeable.

My dealership uses Shell non-syn if they change the oil on my '07 350GS, which they recommend every 5k mi., which is why I change my own every 7500k using Mobil 1. My wife's '10 uses synthetic, per Lexus, therefore Lexus recommends changing it every 10k miles.

If that tsb came out back in 06, all 2007+ manuals would of suggested 5w20 but instead still says 5w20. If you have a pdf of that tsb please atach it as I would like to read about it.

It only says for the 2006 model, 2007 engine different then 2006. Well maybe for a 2006 its 5w20 bu not for the gs350.

it says only 2006 because if you look at the date of the TSB we didn't have 2007's

It also syates checkin oil cap of what grade oil to use, my cap says 5w30. If it came out in 2006 i think all the 2007+ would have 5w20 on the oil cap, and in the manual. My 07 is a very late 07, it was build 08/2007 and sold 10/2007. Thats 2 months before 2008. I am not trying to argue or flame you, just pointing out the facts. If by any chance you have a tsb for 2007+ that says to use 5w20 please post it.

I'm pretty sure my dealer is still using 5W-30. But I did not check.

What the hell's the difference anyway between 30 and 20?
