6G Celicas Forums

I'm sure theres a thread somewhere, but i just figured i might as well open a new thread since theres a lot of new people on this website. So back to the question, What's the best oil to run, or is the synthetic oil better?

Mobile 1 - 1000 5w30 full snythetic is proven the BEST lubtrication in our engines particulary

if you do synthetic do you have to change anything before changing oils

no, unless you go to a shop they will try and sell you an oil "flush" which is a horrible thing to do..

Be weary of full synthetic, it works well, but it's known to mess up the seals. I put it in my car, a month later my oil crank case was empty. Found this out when I went around a hard turn and actually heard my engine grind, and my oil light flashed on. Stopped at the store, and found my oil empty and had to put oil in it on the spot.

Now don't get me wrong, I believe that full synthetic works, but not on super old engines. And honestly, my car only has 80,000 miles. 7A-FE.

ive heard that when you change your oil that you have to change your seals but do you feel good power or what>

i use redline on my car. the celica gets mobil1 full synth.

you use redline on your car? whats that im illiterate

Castrol Magnatec (Which is Semi-Synthetic) for 3S-GE and 3S-GTE,

wont be too bad for the *S-FE either, But not critical, It's no high performance engine.

There are certain conditions to be weary about when choosing a fully synthetic oil, search the net. The same things apply to oil flush aswell. -- For example, an older engine where organic oil residue is creating a seal against a worn seal, a fully synthetic wont have these same properties.

I highly recommend oil catch tanks too, Install them and you'll see how much you're keeping out of the intake system after a few drives.

Oh yeah, Redline oils are said to be the best for our cars, Especially our gearboxes and diffs.

valvoline full syn is what i use, its pricey but well worth it, i currently have it for the 300k miles warranty by valvoline if you registar it before you hit 75k miles

Yea, I'm joking.

Purple Royal has been proven to be the #1 oil that you can use. But due to the price differences I stick with what ever is cheapest in synthetic at stores. There's a PDF file somewhere that proved this with cylinder tests.

I'm using AMS oil right now in my 3S-GTE

very true, but even after seeing that pdf file some members said royal purple was cheap and wasnt that effective. So who do you believe the actual tests or people's testimonials?

Once you go synthetic there is no turning back right? I mean once you start to use synthetic then you cant go back to semi-synthetic?

I personally wouldnt waste my money on synthetic for the weak 7afe, and 5sfe economy engines. Unless of course your 7afe or 5sfe is turbo charged. Then thats a different story.

I use synthetic on my weak n/a 7AFE, I've always used synthetic in all my cars. Depending on the budget, sometimes I switch between synthetic blend and full synthetic. I stay w/full synthetic if I can though. Right now I've got Mobil 1 Synthetic in my car, 10w-30. Very happy with it, motor pulls strong and feels great. Low end torque is about all my motor has to offer, so I do what I can to maximize its offerings.

Ultimately, whatever oil you use, NOTHING substitutes for regular fluid changes and maintenance.

On the 5sfe or 7afe there is no need to waste the money on Mobil 1 synthetic or anything like that. The 3sgte, maybe, new performance car, yes. On these older economy engines all we need is regular old oil.

I personally use the Valvoline high-mileage synthetic blend in both my cars. It's inexpensive, and works really well.

ya its kind of a waste to use synthetic blend on 7afe and 5sfe. I mean only if you're going to race your 7afe or 5sfe(which isnt really a good idea). I use valvoline, castrol, or any high mileage over 75,000 miles synthetic blend.

gtx!

I heard the castrol edge was good stuff, but i don't see it worth the price difference.

The use of oil also depends on the conditions of your environment as well. If you have reg oil and live in cold areas like where in live in Canada were we had a record low of -58 degrees celcius, I definitely recommend using a mix of 50/50 or 75/25 synthetic to regular oil. You can even use full synthetic but make sure you get new seals. You might find leakage.

Right now I use full synthetic Royal Purple 5w30 and I have only used that for my oil changes.

Peace!!
