72k too late for synthetic oil? - Toyota Nation Forum : Toyota Car and Truck Forums

Obelix · 04-23-2005, 12:11 AM

Hi everybody!
I got a 99 Camry V6 and had the car since 58k miles..
I change the oil every 3k whit the regular Castrol GTX...
Now its got almost 72k and after a research i decidet to switch the oil to synthetic (Mobil 1)...
What do you guys think? am i doing right ? Does anybody ever had problems ? Because i know that high milage switching can couse leaking or something like that ?
and do you think a good flushing is neccessary? i am going to put Mobil 1 synthetic oil ! + K$N oil filter or Mobil oil filter... Can you please share your espirience with synthetic oil please... THANKS!

I changed over to synthetic at about 190K km.....and now I'm planning on changing to synthetic atf at 225k

my maxima has been running on synthetic since the beginning..

Synthetic oil does in-fact have smaller molecules synthetic lubricants... however most say it is a myth you can't go back from dyno oil.

my suggestion to you is just switch and see how the car runs. If, by some chance, it starts to leak, you can easily switch it back to dyno and be on your way. However, i believe if your car doesn't leak now, i highly doubt it will start leaking.

however, if you flush + go synthetic ... maybe , just maybe. flushing would help get rid of carbon deposits, but switch to synethetic first and see if you can tell a difference.

Be careful. once you switch to synthetic, you should really keep putting it in. (unless you flush it out again) but @ 72k you should be ok tho since it is pretty early in the cars life.

Switching to a synthetic oil can cause piston rings to leak and in some very rare cases, piston slap or crank vibration.

I'm @ 170k and several different shops and mechanics have told me not to switch to synthetic, so I'm not.

I just use whatever the dealership uses.. so if they use regular old 5w30... that's what goes in my car.

But to answer your question... my friend swapped to synthetic oil at 160k mile on his '92 Accord with no problems..

Always swtich over ASAP.
Synthetic and dino mixing, will mix fine. Swap back and forth as much as you want...

But once you swap to synthetic, you should STAY with synthetic because it is superior.

nope, i changed over to partial synthetic at 90,000 miles in my 2000 camry. go for it

95camguy · 04-23-2005, 06:23 PM

72k is nothing... u should be fine

lenjack · 04-24-2005, 02:58 PM

Not a problem...and you can swap back & forth at will.

It is never too late to switch to synthetic.

A guy made a point once, something to this effect: "synthetic oil doesn't create oil leaks or destroy seals, those leaks were already there but synthetic oil shows you where the leaks are."

I swapped synthetic Mobil 1 into my 160,000 mi 3S-FE and there were NO leaks at all.

It's never too late, but once you go synthetic, you can never go back.

i just switched to m1 full synchethic, 99 1mz-fe, at 118k miles, i've heard difference opinions about switch to synthetic and can't go back while other said there is synthetic blend with regular oil where people don't wanna go full synthetic yet.
i am just hoping there is a less chance of sludge build up on my engine after switching.

yeah, i have 180k on my cam and was trying to decide wther or not to switch to synthetic. if not i was just gonna go with some more high milage.

i was also considering a synthetic blend, does anyone know if this is decent.

I disagree - have gone back twice --I am at 170,000km & no leaks or oil burning. Will try & post a ggod oil info site here --http://theoildrop.server101.com/cgi/ultimatebb.cgi
Hope it works

Synthetic blend is good. Ford recommends using it in all their new trucks
