Just wondering what type of oil all you use.and the weight? I have a 3.0 engine and was just wondering what type and weight you recommend.

Poul D'eau

Castrol GTX 10w-30. You might want to look at 5w-30 if you spend any time with the temps below 0*

My 3.0 has 156,000 miles and leaks a little from the oil cooler, I like castrol 10W-40. I think something a little thicker is better for a higher mileage engine, just my opinion though

MRunner

I use 10W40 also

I used to run 20W-50 but decided I wanted better gas mileage and have been running 10W40 though it leaks more now.

Is 20W-50 to thick to run in a 3.0, and will it do any harm. I no it is not good in the winter, but what about summer?

Elton

i like to use 10w-30

bruzer

Penzoil 10-30 in the winter, 10-40 in the summer, and would never run anything thicker, the 3.slow has a hard enough time as is.

pruney81

In the 80's the 22re's called for 20W50 and I use to run it in my 86 and 87 runner's but I've never gone above 10W40 for the 3.0, but I suppose in the summer it would be fine, but I would definitley use 10W40 when it gets cold

i run 10-30 all year long.mobil1, QS torque power, or amsoil.

10w-30, if you change it every 3k there is no point in buying all that high mileage, castol, good brand junk. Go to walmart and buy thier brand, its made by quaker state or havoline (texaco) last time I checked. Last chang I put in havoline cause it was on sale.

If you plan on having the oil in thier for over 5k def buy the better stuff.

I live in Texas (so temp. is typically between 70 and 110). It ran just fine, though I lost 1-2mpg or so from running it.

I definitely agree with Bruzer. I put Penzoil 10w-30 in mine year round but '40 wouldn't hurt during the summer. I use high mileage oil--supposedly it helps the seals, but it's probably just hype. Ah well, helps me sleep at night.

How 'bout oil filters?? What do yall use in your trucks? I try to use Toyota filters everytime I can, but if I run out, I'll buy a Double-Guard Fram from Walmart.

PS Walmart's SuperTech oil IS made by Quaker State.

pruney81

I use Toyota filters but I doubt it makes a difference

youngbuck

5W30 year round, but I got a lot of extra 10W30, which I might run in the summer.

Mister Willie

I use what the manual recommends. I think its 10w30.

91_4x4runner

I typically use that FRAM Double Guard filter just because I'm too lazy to source anything else or buy from the stealership.

91TPU

it is actually said that fram filters lower oil pressure, i still use em tho, its just the easiest source for me

Keggo

I'm using Castrol Syntec 10w30 in my engine right now... runs so smooth. I also use Fram Doubleguard oil filters.

SolidDigital

10w40 and sometimes 20w50 in the summer..

edit: usually buy whatever's cheapest or on sale and change it out every 6 months or 3k miles. I get either the supertech filters from walmart (which are better than fram) or the motorcraft fl400s which is a oversized filter that just fits in and has the same bypass valve specs as the stock filter.
