oil, what's the best? Options

[garin]

i wanna switch to synthetic oil for my 94 gt. i have castrol gtx 10w-30 and a fram filter in it now. i though about royal purple and castrol sytec. i heard that castrol syntec isn't the best synthetic oil and i also heard that royal purple isn't good if your car has over 90,000 or so miles. so i just wanted to hear what people have to say. my friend, who has a 2000 gts said that mobile 1 and an oem filter is what people recommend for his car. so what is the best synthetic oil and filter for a 6gc?

[p0lish]

MOTUL

[devilsden97]

mobil1 and oem filter

[p0lish]

mobil1 and oem filter

please do a test - after 10k km change your oil, first using mobil1 5w50 and then MOTUL
after draining the old oil compare the color, texture and density of both

Toyota dealers recommend Mobil1 for all Toyota cars but the again they used to recommend Castrol a while back....

[Rusty]

what visocity would you recommend?

[devilsden97]

10w30 (assuming your in a moderate climate. IE: tempuratures between -10° and 100°f)

mobil1 and oem filter

please do a test - after 10k km change your oil, first using mobil1 5w50 and then MOTUL

to be quite honest ive never heard of Motul in my life.

Motul 300V 15W50 Competition, and yes it is nearly 2x the price of Mobil1

[GotToyota]

Amsoil. http://www.amsoil.com/catalog.aspx?subcategory=40

As for weight, I prefer 5W-30.

There are many on-line retailers that have that in stock. Google it to find the one you like most. It is also 40% cheaper in US than it is here. For that price I would not hesitate a second to give my engine one of the best Oils there is.

[99Celica]

x2 for Amsoil and mobil 1 synthetic, although I needed to top off Amsoil every so often because it was thin

[808celica]

was using castrol syntec 10w-40 with k&n filter.

then suddenly changed to mobil 1 10w-30 with mobile 1 filter. both are good but i get slightly better gas with the mobile 1

**used both 30 and 40 for both**

[trdproven]

Castrol GTX 10w-40 with Toyota OEM filter. Of course if you got the cash get Royal Purple oil. Reason for 10w-40 is when your car is not new anymore like ours and the temperature. I think thats why me and 808 use the same oil weight.

i ended up getting castrol 5w-30 synthetic blend for now. didn't put it in yet.

[Rayme]

You can't go wrong with AMSOIL, I have yet to read anything NEGATIVE about that oil...I can't say the same about mobile1.

-remy

[garin]

yeah maybe next time i'll give it a try. i hear good things about it.

[presure2]

X1000.
after seeing how castrol reacted in my motor, then how CLEAN arts motor was using mobil1, i switched to mobil, and will never use a castrol product again.

[roelamizzle]

I work at the ExxonMobil refinery in Baytown Texas and recently took a sample of my used Mobil 1 5w30 with around 6k miles on it into our lab for testing. They reported back that the oil was still good for continued use. Of course I changed my oil anyway but I will continue to use the Mobil 1 brand. Today a saw a new blend in Walmart, 0w30 its supposed to improve gas mileage by 2%, gonna try it for my next oil change.

[aflacattack]

i've used alot of different things; 5w30/10w30 castrol full syth, mobil1 5w30/10w30 full syth, royal purple 10w30, if i could find motul i'd try that too. but no luck. course i didnt look so hard.
never noticed a diference betweeen mobil1 or royal purple, but my car doesnt like castrol lol!
speaking of which, its time for an oil change...

[SlickRick]

Ah yes the great oil debate!!! I run repsol full syn. oil. Its what is used in Honda race bikes, its 10w60. But i should be using a straight 60w out in hot ass phoenix.

[FreddyTheOthaMea...]

been using valvoline full synthetic 5w30

[SlickRick]

in my full blow race 600rr i use 5w or Zero weight

[Rayme]

Toyotas will last over 300 000 KM with deer piss as oil, I don't really think it matter much anyway in our puny 135 HP engines.

[Taskbot]

I think I will use Mobil 1 for my next oil change which happens to be Tomorrow. However, I am going to have the same problem as reko I predict. It boils down to either motomaster or fram. (Mountain Dew or Crab Juice)

The great oil debate indeed.

What kind of oil is the best to use has been a topic of heated discussion for years... probably since the beginning of cars, actually (maybe earlier). There are so many people who SWEAR by one brand or another, and will even go on and on about studies and lab tests and personal experiences about how this oil is better than that oil and so on. It's worse than discussing which religion is the best one!

The real truth of the matter is that you can put the cheapest, bottom of the barrel oil in your car, drive it like you stole it, and never have a problem. IF. If, you change it regularly. Unlike what brand of oil you're using, how often you change your oil really DOES matter. Change it regularly and keep it clean, and your engine will run great for years to come. Spending a ton of money on some new super-oil might make you feel better, but your engine doesn't give a rat's ass. It just wants oil that's clean

I think this guy here put it best:

Toyotas will last over 300 000 KM with deer piss as oil, I don't really think it matter much anyway in our puny 135 HP engines.

Yeah.... that's pretty much right.

[D-Man]

^ Thanks doc. i'll be sure to change my oil and put in clean deer piss [/thread]

I agree with most of that, but I wouldn't say bottom of the barrel oil is a good idea. I was getting ready to start my swap so I used some recycled oil that smelled like axle grease when I poured it into my 5SFE... less than 50 miles later it spun a bearing... my 3SGTE will get none of that.

[Dr_Tweak]

Okay, not BOTTOM of the barrel

In all seriousness, I run NAPA oil in just about everything with great success.

[Hanyo]

from my experience.

If you change your oil frequently and consistently, it doesn't matter what oil you use or the filter.

[Remy]

I use synthetic oil only, mobil 1 with mobil 1 filter every 3k.

[RisingSun1]

I use Royal Purple 5w-30, and my car has 154,000 mile; no problems at all

[AE102]

been using valvoline full synthetic 5w30

good stuff - i use there Synpower in 0w - 40 in all me motors. i used to use mobil 1 but our local trade counter doesnt stock it and large motor factors charge to much. looking at £40+ for the Mobil whereas i get Valvoline for £25. i changed to valvoline about 5 years ago and havent looked back. as for filters - like others have said dont use fram. over here i use blueprint filters - exact same as genuine toyota ones but half the price. never had a problem with any blueprint part.

for higher mileage engines i've heard the "maxlife" oil Valvoline comes recommended but i have no personel experience of it - i have no probs in a 3s-fe i have which runs on Synpower and that has 110k miles on the clock.

[mariosdarkworld]

I use K&N oil filter and it works great as for oil i use Vavoline 5w30 in fall-winter 10w30 spring-summer. My car doesnt like 10W40 cause its harsh on the rpms ha
