Can you run fully synthetic?

[JetspeedCamry]

I'm running Penzoil HPR 30 at the moment. Does anyone know if my motor, or any other Camry motor can take on Castrol Magnatec, or a fully synthetic thin oil? Would it be too thin? And what would we the difference in the way the motor spins?

The reason I ask is a friend is running Magnatec, fully synthetic oil in his 86 Celica. Even when cold this oil was soooo thin, like water. And I said I don't know If id recommend using it. He seems to have no probs running it tho.

Thanx.

I've used castrol txt 5w-40 on the 3rd gen camry with 3VZ-FE for 4 years and now use castrol magnatec 5w-40 for 4rd gen camry with 1MZ-FE already 1,5 year and don't have any problems. I change it every 10000kilometers ~ 6200miles.

Synthetic is preferred. There is no reason to use inferior dino oil.

AMSoil is the best
After that Mobile 1, becuase it's good, but easy to buy.

That's completely incorrect. A lot of times if you switch to synthetic you will start leaking oil because the dino oil made a seal wherever leaks were possible. I say especially if it's an older car, just use dino oil and change every 3k miles and enjoy years of reliability.

This is what I was thinking. Although some of my seals are new, I would've thought that the synth oil would leak because it's so thin. When we did the change on this Celica, it was like water...i can't imagine how it lubricates that well on older engines. Perhaps it's designed for more modern engines which run synthetic from factory?

Bottom line..just keep using normal HPR 30??

that's where you are wrong

synthetic will alwasy be better because of less wear and tear on the moving parts
if you spring leaks, the leaks were always there anyway, and the use of synthetic oil will just show them to you. If the leaks are big enough to worry about, then they should have been fixed in the first place anyway




only tip when it comes to oil that I can say is this....don't use 15w50 when it's below zero outside...I changed it once it hit april this past year, but the crazy weather kept on dipping below zero, and the car started REALLY hard in the mornings....that stuff is thick....

I like Synthetic best.
Why would you want sludge preventing leaks anyways?
Gunky enough to stop a leak, gunky enough to stop a journal or passageway.

Ever hear an engine seize?
It starts as a screech, followed by either a loud bang and then parts clanking around as your engine spins to its death or an even louder silence as your motor fuses into a one piece unit.

No core exchange for you.

I have been using Mobil-1 5w30 since the 1st oil change on my 1998 Sienna XLE. After ~90K miles, no signs of leaks yet, no valve chattering either.

Excuse me but leaks have nothing to do with synthetic oil and everything to do withvalve stem seals that are ALREADY damaged and should be replaced.

Another synthetic happy customer. ^

If I had this Camry fresh from factory, it would know little dino.

I have searched on this site and the only slings at synthetic is there was claims that the cars were leaking more oil. They were leaking oils before but now its more. Hey, when seals fail, they do not get better, it gets worse. There is pressure in that engine case just pushing oil out wherever it will go. Do what you gotta. My car stays synthetic.

I am going to volunteer my car for a test. Look for post.

Synthetic is the only way to go on a newer motor and infrequent oil changes are no problems if your woman is driving it because then she can drive it longer for longer periods and you won't have to replace it as fast. Probably not many synthetic fans around because its probably best for racing. The girls like to beat on the cars to.

Supposedly runnin syn after many miles of dino can break off carbon chunks and stuff and clog a passageway or oil pickup tube. Run engine tune-up for an oil change or two before before switching is often times recommended. Anotherwards if you want to run clean..., start clean or get clean first.

^WTF???
Non English?? Sexist??

[amerikim]

She souded like my ex, we always fought about the car care. She hated i drove and I hated I fixed, cleaned and paid.

I flushed engine out before I went syth, no kerosene, but just single run of crap cleaner at Jiffy Lube and then put Castrol Full Synthtec in. Cars instantly smoother and stayed that way for more then six months, changed to Mobil 1 then.

Yeah, but they wouldn't have leaked had he stayed with dino oil. But instead, it then comes through. How is that a good thing? Switching to synthetic isn't a mandatory need. I know tons of cars that haven't run it and have lasted forever. For example, I have 202k miles on my car and I run NAPA Premium 5W-30. It's not needed, it's just a waste of money


Stick with standard oil. You'll be fine as long as you treat your car good, and don't beat on it

You're not suppose to switch to synthetic if your vehicle already has a decent amount of mileage. Doing so will cause leaks to the engine seals because synthetic is so much thinner than dino oil.

If you change your dino oil more frequently than regular interval, it gives same effect as using synthetic.
