![Question](https://www.clublexus.com/forums/images/icons/icon5.gif)
My new GS430 just turned over 1100 miles and I took it to a SuperLube and had the oil changed to Mobil1 synthetic 5W-30. I just took it to the dealership and they told me that I should have left the original oil in for the full 5,000 miles. I have always changed my oil this early in a new car thinking I would get any excess metal out of the system early. Since the break-in period is 1,000 miles, I am confused. Does anyone have any info on this? Have I really screwed up?

i think the way engines are made these days, there's not much to sweat. personally, i don't like switching over to synthetics too early, but it's more superstition than diligence. i can't see why the dealership would have a qualm with what you did; they probably just don't like the idea of any outsider messing with the car.
i give little weight to the notion that you have to use the dealer for everything. if you know what the service entails, and you convince yourself that there's nothing special about a given task, and you have a long relationship with a mechanic who knows how much you care about your car, then why trust some stranger at the dealer? i don't even let my dealer wash my car cause i think i can do a better job. exercise good judgement and you'll be fine. don't get paranoid; it's unhealthy.

My father-in-law did all the primary research (and filed the patents) for Mobil-1, so I think his advice is good!
Anyway, he says synthetic oils are a waste of money for cars if you change the oil and filter frequently anyway.

This is directly from LEXUS:
Can I use synthetic engine oil in my Lexus vehicle during its break-in period?
Synthetic oil can be used at the first scheduled oil change. Please note that the use of synthetic oil does not extend the recommended oil change intervals. Please refer to the Lexus Owner's Manual Supplement for further information regarding the proper maintenance schedule for your specific vehicle.
If synthetic oil is used after that time, it should be the same SAE (Society of Automotive Engineers) weight specification and meet or exceed the API (American Petroleum Institute) grade specifications listed in the Owner's Manual. Even if synthetic oil is used, we do not recommend longer oil change intervals. Once synthetic oil is used, it is best not to switch back to petroleum-based oil.

I have a 2000 GS 300 and have been taking it to the dealship for the oil change @ 95.00 each time. I noticed you took it to a Superlube. How does that affect your warranty? I have some maintence experience and normally change the oil and brakes and other general itmes on my other car. If I can get around from paying the dealership $95, this would be great. Any advice!

No need to go to the dealer for oil changes. Take it anywhere you want or do it yourself. Just keep the receipts to show the dealer when/if you need warranty work on the engine.

Once synthetic oil is used, it is best not to switch back to petroleum-based oil.
Every synthetic automotive engine oil is petroleum-based. The petroleum oil is chemically synthesized to better withstand high temperatures (resist burning) and for lower viscosity at freezing temperatures.

Chowder - Yep, I've heard of the policy of not switching back & forth. I recall that it's based on the fact that syns don't break down & leave the carbon deposits as readily as conventionals - it'll actually clean up your engine with regular use. I'd imagine that once it's cleaned up, U wouldn't want to start using an oil ( read: conventional ) that's more prone to breaking down & have to start all over again. The biggest difference in a syn's makeup is that all the oil molecules are equal in size as opposed to the irregular shaped molecules in a conventional oil. This helps ensure stable shear strength throughout it's entire viscosity range & thus it protects better at high temps & pumps easier at low ones.

the only wives' tales i attend to with oil are: let the engine break in with conventional before you switch to synthetic, and don't switch from conventional to synthetic for an older car to avoid the possibility of creating leaks. switching back and forth mid-stream might be defeatist, but that quoted statement somehow implied "imprudent" to me, when it can't be.
i wanna know what lexus did to allow them to recommend oil changes at 5k-7.5K miles with conventional oil. when i switched over from conventional to synthetic, i did the change myself so i could see how the used oil was (not pretty at 5150mi). maybe it's all a figment of my imagination, but my GS felt smoother through shifts and acceleration almost immediately after she got some synthetic in her.

Syn. does seem to smooth out the engine better... It could be mind tricks.... I agree with the masses, change the oil every 3000 miles and it will be fine....
What about oil filters..?
I've been using Frams filters.. versus the Lexus filter.
What are the pros or cons of not using a Lex filter if any??
I'ved used both Syn and conv. oil in my SC4... The past years it's been both syn. at Wal mart for $24.88... Conv. oil is $15.88(on sale $13.88...)
Just make sure they put ALL the screws back in the dust cover...
Let them(service manager) know up front you will be checking... It is Wal-mart....
But it's a great pr$$$..... $95.00 for an oil change is crazy....

Thanks..... I should've searched the threads better.....
I'll search for a Mobil 1 oil filter..... or even a K&N oil filter now..
I've heard K&N makes a good filter...
