Best Motor Oil for your Toyota, and coolant too Options

[hurley97]

If you had any questions as to what kind of oil and/or coolant is best for your Toyota, this might help.
Its from a Toyota Complete Maintenance Care booklet they gave to the Service Advisors at the dealerships...

6 out of 10 [Toyota] vehicles come with Exxon Mobil as "factory fill"

nice find steff i take it that job has its perks

[massbrandon]

Hey Steff not to hijack your thread but I was wondering if anyone had used Royal Purple motor oil? I did a search and just didn't get any good feedback so I wanted to see if anyone was actually using it. Thats a very interesting find though.

A note on the coolant.

Toyota red doesn't have silicates in it.
This is because Toyota believes it damages water pump seals.

Whether or not it actually does, :shrug:

Engines that are half aluminum and half cast iron tend to corrode more because of the electron differences between dissimilar metals.
Electrolysis.

Basically the main anti corrosion ingredient is phosphates.
Phosphates work great in pure [distilled] water to prevent corrosion.
However, in hard water [more impurities, such as metals, whatever] it doesn't work as well. The harder the water the less it protects.

Basically, if you use Toyota red in your engine [I do] make sure you use distilled water and not tap water, especially if you have well water.

im using royal purple and it works fine, suppose to be better than mobil1

[NaderG]

what about the transmission fluid ??

[laff09]

Castrol GTX >>> Mobil 1. I fell off the Mobil bandwagon.

[Supersprynt]

Mobil 1 is full synthetic, GTX is not even a blend. Are you basing that off opinion?

Yes.

Ok.. Why would one use full synthetic on a 13 year old motor with original seals/gaskets sans valve cover gasket? For my application and experience using BOTH brands NUMEROUS times, GTX takes the cake. Mobil 1, your normal 10w-30 Mobil 1, burns up quicker than GTX..in my experience. So I'll continue to use GTX until I find something better or decide to reseal my engine
Im looking to keep the oil in my engine, not all over my white driveway. hehe.

Not tryna clog this thread up anymore

Toyota fluid of course. I just thought people would find it interesting that Mobil 1 is considered Toyota Genuine Motor Oil, and I thought that comparison of the corrosive qualities of coolant was good info too.

so your basing your opinion on the fact that your engine is 10+ yrs old, and needs major mantinence?
lol
steff has the right idea.
if your having your car regularly seviced by toyota, (or better yet, learn to do it yourself!) chances are its not going to be leaking fuild all over your driveway and burning in your car.
just because castrol is thicker dont make it any better, thats for sure.
after seeing what my 150K engine looked like when i pulled it (yes, it was still running..and pretty decently actually) after using castrol for years, how black/red it was, i couldnt wait to get the newer, mobil1 fed all its life 5s.
i know this prolly aint the thread for this but, steff, you know me. i gotta do it...any chance to show these pics i do!! haha
ok so, heres what happens when you dont follow the mantinence schedual, pass on oil changes, run it low on oil, leaking ect, this is ~150K miles.


and here is what a well maintained, low milage (~52k miles) will look like when you use mobil1 as suggested by toyota.


ill take the latter, thanks.

Pressure , that is a HUGE difference , lets say that an engine has arround 98k on the clock , been neglegted and i want to bring it back to life ... if do the over-due maintenance , would it make a difference , or is it too late ( oil already is covering my cams ) ?

[alltracman78]

Running good oil through the engine and changing it regularly will clean up ALOT of crap from the engine.

I use Royal Purple every thing in my car...Purple Ice coolant addative, oil, tranny fluid, i used their assembly lube puttin my buddies 305 back together. Its great stuff. I change my oil every 3500km and my engine is as clean as a whistel inside. Well, as clean as an engine with 80K km on it can be. But its good stuff, im a bit over my oil change mark now *around 4600km* and my oil is still pretty clean.

But yea, i always notice when im at the local dealership they got mobile 1 and toyota oil on the shelf. They also have mopar oil filters too. Didnt ask why though...

[hellsyphon]

Royal Purple is awesome Group IV synthetic oil. Only downside to it is the 40 weight sheers quickly down to 30 weight and you cannot run an OCI as long as other conventional Synthetics. Mobil1 30 weight oils are now group III synthetic, which does not make it a true synthetic oil anymore, but Toyota motors return excellent UOAs with them.

[SlowCelica94]

In my old 6gc, I always used Moblie 1 full syn with a bosch filter. At 3k miles, my oil still looked new.

So what am I getting at? If you're on a budget, just spring for moblie 1. If you have extra cash, upgrade to Royal Purple, it knows how to rock.

a lot of car manufactures are recommending mobil one these days. new evos, and even some porsches have "mobil one only" right on their oil cap. part of me thinks this is great, while another part of me wonders how much of that is a marketing idea. i mean, while its a great product, mobil had to have paid toyota some money for them to say that.

my current theory on motor oils is this:
if you have a motor, thats in good shape, help keep it that way with a synthetic like mobil one.

if your motor has a lot of miles and has a been on cheap oil all its life, then the damage is probably already done and there is not a whole lot you can do.

over all, the most important thing to do is to change your oil right at 2-3000 miles, regardless of the brand.

[Delta_Phoenix]

been using GTX HM 10w-30 for about 75,000 miles now, and still runs like a sewing machine. i'd love to run the mobil 15,000 mile synthetic or whatever, but 180,000+ miles on the 7a makes me expect massive burnoff.

it comes down to personal pref. i guess. i'll trust any oil that sponsors and has success with F1 cars (Castrol, Mobil, Valvoline), but i've had a good experience with castrol. the only oil i've ever heard negative comments about is quaker-state. i've been working at autozone for over a month, and haven't seen 1 quart of quaker go out the door. i just sold 90 bucks worth of castrol syntec the other day.

and if you'll remember, the WRC 6th gen was covered in castrol decals
