Hey guys I have a 2003 TL-Sw/17,000 miles, I've changed the oil many times.Last time coming from dealership.I was wondering when is a good time or right time(Does it even Matter??) to think about switching to synthetic oil (Mobil One),and is there any negeative effect or positive effect I might face from using synthetic oil too early.And whats do people out there use 10/30-15/40.......Thank You In advance

optomos

You can start using it right now. Just use what viscosity is printed on the oil filler cap and I wouldnt even worry about flushing your engine with that many miles.

If you do use M1 use the extended mileage series.

phipark

How about now?

Phesto

thanks just thought i read that it was good to use Regular Oil up till a certain point.My next Oil change at 18,000 will make the switch

khoifl

I say as soon as possible and 5w30 would be nice all year round.

drcookie

With the mileage that you have, it should not be a problem to switch it. I did mine when my TLS was at 5,000 miles. I switched it to Mobile One 5w30 and change it every 5k miles.

Hope this helps.

Cheers !!!

Phesto

Thanks Cookie,Ill follow word for word

Yes...I got the oil changed at the dealership few weeks ago with Mobil 1 5W30 Syth oil

samkws

u r from san fran, so 5W-30 would be good enough

i recommend amsoil or motul, but more expensive thou

Phesto

Do you think the amsoil is worth the difference in price??
I'm on the fence as to which one to buy

ou sig

No

just get Mobil 1 synthetic with the Mobil 1 filter and you will be good to go for at least 7k miles between changes. I usually do it around 7-9k miles (whenever I get to it in that time). I switched at 60k miles (all with dyno oil) and I am now to the sad point of 100k miles. There are no leaking problems at all - I dont believe that is a problem now with modern engines and oils. oh ya, I use 5w-30 year around.

samkws

i track my car so i think it's worth the price, it's only like 2 dollars more per qt

PenancE

trust me HE DOES TRACK LOL

sam whats ur tl mileage on it now? i plan on buying a new tl, (mainly a 02) before i hit 100k

JetJock

I switched to synthetic (RedLine 5w-20) in both my new TL's. The 2002TLS ran great, now I've got a '04 TL. Both were changed from dyno to synthetic at the 2nd oil change. The '04 TL had approx 3800 miles when I switched.

optomos

Amsoil oil is good for 15K and their EA filters are good for 25K or one year & is high capacity.

I would go with the Series 3000 5w-30 & EA filter for a one year oil change which is what I run. The series 3000 will save you some gas to.

You can switch any time you want.

Phesto

great info guys

paulboo

I am thinking about switching to synthetic oil however my car is at 63000 miles. Is there any special things I have to do to prep the car for synthetic oil at this point? Like motor flush, etc? Thanks

khoifl

No, I don't think so. Just regular drain and fill. And make sure, you get a decent (good) filter.

paulboo

Thanks! That was quick! LOL

Phesto

Go with amsoil i ended up doing that

ultimatetl

where do you guys get the good quality filters and amsoil oil?
i usually go to Wal-Mart to get Fram filters....

Fossil_TL

I switched to 0w20 mobil 1 synthetic around 48000miles, and I change oil every 5000 miles, I get excellent mileage and also very good starting in freezing cold michigan weather.

ou sig

nope, I switched at just about the same time - just drain and fill with the good stuff

Fram filters are fine...just not the best by any means. You can get the Mobil 1 filter at Auto Zone, it is a much better filter for a few more bucks. I wouldnt spend the extra money on Amsoil on the other hand - you can get the Mobil 1 synthetic from Wal Mart in the 5Q jug for a little over $20

paulboo

0w20?! What is the difference between 0w20 and 5w20? 0w20 is fine? You change your oil every 5000 miles? I thought with mobil 1 synthetic you could go all the way to 7500 miles between changes or even 10000 miles.

Phesto

I think amsoil even advertises 20,000 miles , i would never wait that long myself though

paulboo

Use Mobil 1 oil with a Mobil 1 filter and change it at the reccomended oil change interval(7500miles), sound good? OR Is it still too soon and wasting my money? Will switching to synthetic this late into the car's life even help or make a difference?

I just hit 90k and I'm thinking of making the switch at the next oil change. I go to the dealership to get it changed but does anyone know if they have the mobil1 there or do I need to buy it and bring it over there when I go.

Depend on your dealer. Some use Castrol Syntec, while other use Mobil1. Besides, it is cheaper to buy from outside. Dealer will charge you about $30 more for synthetic. In the end, you'll be paying for about $40 for 5 qt, assuming $10 for dino oil and $30 for the synthetic upgrade. A 5qt jug at Wal-mart is $20

samkws

a lot, working with my car

now is at 88k km

I switched to Mobil 1 5W30 after all the freebie oil changes that the dealer gave me. Initially, they didn't seem to mind me bringing in my own jug of Mobil 1 5W30 but recently, the service rep sorta read me the riot act about sticking to 5W20 and how 5W30 "might" affect my warranty so forth,etc...

I guess Honda was telling them to stick to the OEM spec oil or try to push for the Motul 5W20 they have available for close to $80.00.

Haven't seen much of Mobil1 5W20 here in Toronto.

pzero23

I think the same TL's from years 99-00 have recommed to use 5w30 and the same cars from 01 and up are suppose to use 5w20. Maybe they use 5w20 just so when they do testing they can say their cars are more efficient run. Just a thought.

i just switched to mobile1 synthetic this past weekend.. i drove to ohio from tampa with the 10w30 synthetic blend (put about 1500 miles on that oil change), changed it before i came back and now with about 1300 miles on the 10w30 synthetic oil it still looks brand new. the engine runs alittle smoother too.

As for switching, I ask what's the gain over using conventional oil? Will you own the car long enough to recoup he cost or see the benefits?

I've seen "dyno" oil twice in this thread..time to correct that. It's "dino" as in dinosaurs, who created "fossil" fuels. It's not dyno as in dynamometer.

Dino=dinosaur=fossil fuels.
