What oil do you use?

[1st Synthetics]

Ok its time to see what everone is using to PROTECT their engine.

What motor oil do you run in your Truck?

Well I think it's obvious what I use. The proven best, AMSOIL.

[retired2001]

I use Royal Purple and have for the last year. I've gotten about the same service as from Mobil 1 and may at some time switch back, depending on expenses.

[gmcem50]

I used Amsoil in my last Silverado ('89 R-30), but I am using Mobil1 in my current truck ('08 1500) and in my RVs. I would probably still be using Amsoil if there was a convenient place for me to get it. I use Valvoline Synthetic in my Samurai, but I'll probably switch over to Mobil1 in that too. Whatever the dealer puts in the wife's car it what it gets.

[bry2500]

I used Quaker state in my truck and Mobil 1 in my wifes van, I am waiting for UPS to drop off my Amsoil tomorrow. Then I will only be using Amsoil.

[gimme_a_350]

i voted Mobil 1, but I actually use Mobil 5000 conventional oil; I'm in high school and I'm strapped for cash. It's a nice medium between synthetic and 3000 mile conventional.

[nickgiacalone]

I sell to Everyone. Retail, Preferred customers, Retail Accounts, Commercial account, and other dealers.

I live in South Lyon.

[Z71_guy]

i use kendal full syn, because i get it at cost for $2.00 quart

[Pete95Sierra]

I used to use valvoline conventional in my GMC, but now I use Quaker State in my Jeep cuz its cheap at wal mart and ive never had a problem with it. so i voted quaker state

[Stouffer]

Was using Mobil 1 in everything before the turck. Now I swithced to Royal Purple for the truck

[amd's chevy]

I've used Quaker State synthetic for a long time now in my truck. I use mobil 1 in my vette.

[Brig]

Castrol GTX - have used it for years. Good enough for John Force (I'll let his penchant for Fords pass), good enough for me!

[TRPLXL2]

Pennzoil 5w-30 in the trucks, and my dad uses Castrol GTX full synthetic in his street rods.

[mistm350]

I voted Valvoline syn but I actually use Valvoline MaxLife Syn blend on my 350 95 suburban Its has been excellent I have 360,000 miles and used it for the last 100,000k

[SoCal Chevy]

[Rossy]

I first used Mobile 1 in 1980 and with the old corkgasket system could not keep it in engine but I immediately recognized the superior qualities of synthetic lubricants as to how easy I could crank off a 390 Ford at -10°F.
Then I guess it was 86 I started running it in one vehicle at that time, then another and now I have put about 675K on several vehicles with it running it 15K or more between changes. Have not had the first bit of engine problems since that time.
We now have three pieces of rolling stock with a combined mileage of 448K. I also have it in a International 140 tractor, Honda generator, Honda lawnmower, weed trimmer and use it to lube my guns and clean the gas systems on the semi autos.
I also use it in my electric motors that have lube ports. I started this in circa 1991 when I talked with a electric motor rebuild facility in Columbus, Ga. They told me to run Mobile 1 as they put it in all their rebuilt motors and had never had one returned for failure with Mobile 1 run therein.

I have about 80 quarts of it laid in. I run 10W30 even though the new engines say 5W, the manuals also say 10W is fine so it will continue to run it.

Should I get another vehicle and the manual calls for 5W only, then I guess I will switch but I suspect that may be a litte or long while now and whatever it is I can assure everyone the next vehicle I purchase will not have been touched by a UAW worker.

[cmcoram]

Royal Purple in all three: 98 Blazer w/180k, 03 TB w/100k, and the Harley with 10k.

[99'HEARTBEAT]

Valvoline Maxlife Full Synthetic 5-30 with A/C Delco Filter.I changed Oil and Filter around every 4500 to 5000 miles

[ippielb]

Jumped on board with amsoil this change.

[2ToNe04]

royal purple, works best for me.

[Pyro81]

I've been using Mobil 1 in all my vehicles now for quite some time. It's not too terribly expensive and it's fairly easy to find.

And speaking of which i need to change the oil in my truck.

[iPublicEnemy47]

I was using the baisc Penzoil 5w-30 Motor oil. Switched to Mobil1 I love it but im gonna jump boat to Amsoil... I still got 4500 miles to my next oil change thou

[Hummer]

I have just begun to see the purple in just a few places but understand it is good as well as Amsoil. I am not aware of any synthetic having a bad reputation insofar as that goes.

Oh you would be surprised at some oils. I would not use the Purple stuff, go with AMSOIL or even Mobil 1. That purple stuff breaks down real fast and you lose all your protection. They recently just got sued by BP for false adverting also. They can't back up any of their claims the use in advertising. Just trying to save you some money down the road by giving you a heads up.

[leester79]

Valvoline DuraBlend or conventional
Partsmaster

I change oil every 3000-3500 miles. Full Synthetic is a little more than I want to shell out... Durablend is my happy medium. (Yes I know synthetic is probably better....and i can get away with more miles between changes. ;- )

[detailjohn]

AMSOIL 5W-30 truck and car.....

[Marty04Sierra]

I use Mobile 1 in all my rigs...

[canislupis69]

Always use Mobile 1 full syn.

[hmaster77]

I have used the autozone oil on all my older vehicles and never had a problem with it but since i got the 08 silverado i have been using valvoline bc they have the special and i figured since its a brand new truck i would use it
My mechanic swears by royal purple and swears he get 2 extra mpg from it in his 03 f 150 but i just dont like paying 50 bucks to change my oil

[Hummer]

Well here is a a blow in the ear. I am a division director of a national organization and we meet quarterly. Our Southeast area rep always comes and he has a mid size Chevy four door and I know he drives high miles so I asked him how many miles he has on his 02 car. He supplies his own vehicle and is paid mileage. He said 289,000 so I asked him if he was running synthetic and he said he changes oil every 10,000 and uses the cheapest stuff he can get ! ! ! ! He also has the original brake pads/shoes.

This just goes to prove the old saying, just when you think you have all the answers they change all the questions ! ! ! ! Whole thing blew my mind. Also tends to prove the other saying that highway miles are best.

[Offshore24]

Mobil 1. I have used Amsoil in the past but my Amsoil connection retird and it's too much trouble to get it now.

[Stouffer]

I just orderd some Amsoil. Was using Royal Purple.

[1st Synthetics]

Mobil 1. I have used Amsoil in the past but my Amsoil connection retird and it's too much trouble to get it now.

Let me know and I can ship it right to your door at a good price if you want AMSOIL.

[dsfloyd]

Have been using castrol GTX for years (mobil1 does go into the rear end of the truck though)

[vms4evr]

Royal Purple in the Z06 and now the Silverado. Shell Rotella in my beater Corolla. It burns off enough that I don't really change it, just add more ;-)

[Slik]

I voted Amsoil, but I also sometimes use royal purple.

[Henchman]

I use the O'Rielly's brand. Aren't they owned by one the major brands?
