POLL: What oil do you use??
 

I am trying to decide on an oil to use in my runner. Just curious as to what oils you guys are using.

Use Amsoil. I use mobil 1 right now because I'm poor and my pickup needs non-synthetic for now, so I can buy in slightly larger quantities and use it in both trucks.

More Questions for you guys using Amsoil. Which of the amsoil oils are you using? If I remember correctly they have at least three types. Also are you using the extended oil change intervals as they recommend. If so, do you change the filter part way through the interval?

None of the above.

I use Costal (Auto Zone store brand made by some unknown oil company, probably Texaco) Its about $3.50 a quart for full synthetic 10w-30 or 5W-30. All other synth motor oil is $5 a quart and its probably the same thing with all the extra money going to advertising and race team sponsorship and corporate executive quarterley bonuses. :roll:

Valvoline HiMileage 10w40

Dino for now..

Will be switching to Mobil 1 Supersyn soon.;)

Mobil 1 Full Synthetic, 10w-30

Here are the 3 types of Amsoil I use in my rig.

The oil I use is for 25K drain intervals, though the longest I have gone is about 4K so far.

I also use an Amsoil oil filter.
Toyota oil filters are very good, but the Amsoil one will filter down to smaller microns, so that is why I use one now.

I use Amsoil as you can see on my sig.

Good old dino stock oil.

Pennzoil Dino for me...

Redline
 

I'll use Redline or Mobil1.

I hate Amsoil because of their cheesy Amway style marketing.:drink: :drink: :drink:

Castrol GTX 10w-30

the best oil that there is by a long shot, not even a contest, i will stand by it for all my living years VALVOLINE nothing out there better for your internal combustion engine

for instance i bought my old yota with 140000 from the origanal owner who ran penzoil its whole life when the engine blew up at 142000 i ripped every thing apart and nasty crud everywhere the inside of the valve cover was black

my other yoter with 215000 that had VALVOLINE through it its whole life that wasnt blown just needed a valve adjustment was completely clean looking brand new and is still rockin hard

BUT OF COURSE THESE ARE ALL OPINIONS
it just so happens im always right

Same here.

What do you think about blends. I am using QuakerState SUV 4x4 blend oil, because it was on sale and it sounded cool. I have used them the past 2 oil changes and it seems to be ok, should I just go fully synthetic or back to dino? Are there any real benefits to the blended formulas?

I'm using Valvoline Durablend half synth and half dino

I use Castrol 10-30. I've always stuck with Castrol or valvoline.

The only thing I am leary of with the Semi-sythetics is "How much is actually synthetic?" I have never found that out. If it's half then it might be worth it. But It doesn't say. So I stick with the dino brands.

I will let you guess what oil I rely on.... :)

I use whatever the dealer puts in, I believe it's Mobil 1. If I had any place to do it I'd change the oil myself, and if I had any money I'd be using full synthetic but alas, I'm poor and drive too much and live in an apartment.

In the 97 4Runner I use 5W-30 Valvoline

In the 00 Avalon I use 10W-30 Valvoline

I have had great service from Valvoline products and long engine life.

:nerd:

Hey bud, this is the one you will want to use...You can click here

Mobil 1 5w30 with K&N oil filter. I like the fact that I can use a 1" wrench or socket on the filter. I find it much easier in the tight space than using a filter wrench.

same here. i use valvoline max lift 5w30 in my 4runner with fram 2x oil filter. i was using mobil 1 supersyn 5w30 but valvoline was cheaper this time around. i plan on switching back to syntechic, probably amsoil in 6 months.

i ran amsoil 5w30 syntechic motor oil with an amsoil filter in my old taco. i changed the oil filter every six months and the oil itself every 12 months. no problems.

OIL
 

Good ol dino. I noticed a few guys switch between synthetic brands, or atleast imply they do. This is very bad for the vehicle, you should never swtch synthetic brands once you've chosen one you should stick with it. With synthetics the way they protect essentially is the same but the detergents and compounds are so different that you shouldn't change up.

First off you should not have to use a filter wrench you oil filter should be hand tight and i promise it wont leak you should be able to remove it by hand this is why most of them have a little grip tape type stuff on the end

you guys really dont need to run synthetic in your toyotas unless you are in a pre runner going 150mph accross the dessert

you are just wasting money when you could get other cool toys for your toy

look up the designed applications for a full synthetic or even a blend synthetic oil

Redline w/ lexus oil filter. 7500 miles b/t oil changes

VALVOLINE SYNTHETIC 10W-30
fram 2x filter
My other Toy is a 1980 4X4, 20R 4 speed, with 31X10.5-15's, 320,000 miles, downey headers, K&n filter at 80,000 miles, aquired truck at 38,000.

IT STILL SCREAMS! Uses oil only after sitting for 6 weeks or more.

Mobil 1 w\ Mobil 1 filter. I'm a "Mobil" type of guy I guess.

Is the Valvoline Full Synthetic just as good as Mobil 1? A mechanic told me to jut use Mobil 1 because there are too many companies that claim to be just as good. We all know Castol Full Synthetic is a waste of money.

After a lot of research over 2 decades and through personal experience I've rejected Mobile 1 for motor oil mainly because Modile 1 tends to reject heat. Don't get me wrong-it can take a lot heat-far more than any dino oil and just as much as any other synthetic-but it tends to insulate, thus failing to provide one of a motors primary means of cooling off. This places a greater heating load on the engines cooling system, and in a hot climate and/or racing, every bit of cooling capacity helps. I took note when one guy had been studying synthetics to use in air cooled engines and found most of them rejected heat just like Mobile 1, and since an air cooled engine is cooled primarily by the oil, it caused those engines to overheat quickly! He waited serveral years for Valvoline to come out with a synthetic, and when they did he tried it and it worked. Subsequent studies revealed that Valvoline had apparently done their homework before coming out with the product and engineered it correctly to absorb heat.

But this was the late 80's. I haven't kept up with the progess, They all may be correctly engineered now, but I stick with what I know works.

I've lived in deep south Texas for years, and can say that I noticed a difference in engine cooling in the summer when I switched from Mobile 1 to Valvoline.

There's a lot of good stuff on the net now-a-daze I'm sure, so you may want to do some of your own research.

Just my $0.02!

Mobil 1 Full Synthetic, 5w-30. I follows same grade oil.

I use the AMSOIL 0-W30. They say it will last about 20,000+ mi., but i usually change the filter every 4-5k and the oil every 8-10k. Works pretty well for me.

Quaker state 5W/30 full synthetic

Amsoil 10w30 w/ amsoil filter

I use Castrol 10w-40 in my truck. I also use Toyota filters.

I change the oil every 4000-5000 miles. I would consider synthetic if I had a brand new Toyota, but I don't, so I won't.:pig:

mobile 1 10w-30 super syn

Chevron Delo 400 15w-40 w/ factory filter. Changed every 5k. Its a dino oil used in diesels. I use Royal Purple in the drive train. Best combination I've found since getting my Runner at 187k in 2000. Now has 277k and runs like brand new!:D
Synthetics are great. Just be sure to be consistent. and to really be sure do an oil analysis. Some oils can go 10k before needing a change.
