Mobil 1 vs Amsoil

[slostang281]

I tore a LQ4 apart that had right at 300,000 miles and the owner claimed to use Amsoil and changed it at 25,000 miles. It still looked brand new on the inside, after lugging a ten thousand pound truck around all it's life; I was impressed. If I had to choose between the two, it would be Amsoil if I can find it.

15-50? That must be one worn out som'bitch or poorly put together to use that kind of oil in a street car.

Thats what i used, only cause my lifter where worn out lol.

I am old school, I prefer Mobil 1 15w50 in my mustang. I have nothing against amsoil, I just like mobil 1 personally.

I've seen that mobil 1 extended performance at walmart but only in single quarts. Do you know somewhere that sells it in the 5 quart?

That's odd, the Walmart near me has them in a 5 qt jug...

I've run mobil 1(oil and filters) in my trucks since I started buying new vehicles for work.

Currently, my 08 Sierra has just over 180k miles on it and I haven't had any problems. I average 8-10k miles per oil change. It doesn't smoke or use any oil. I've looked in the valve covers and cylinders and everything still looks new to me.

Never tried Amsoil... mostly because it's easier to come by the Mobil1.

Mobil 1... I have never run amsoil, but have never seen anything but good from Mobil 1..

Mobil 1 will do it, if you want peace of mind get Mobil 1 extended performance.

Like I said more then likely I won't hit the 10k mark for at least over a year. This is not my daily driver, just my toy. I want an oil where I'm at peace of mind of it just sitting more then driven.

Check out the forum on www.bobistheoilguy.com

More oil info on there than you probably ever wanted to know.

Amsoil is hands down the better of the 2 but I use Mobil 1 in all of my work trucks simply because it can be bought at Wal-Mart 24/7.

[STRONGNUFF]

I've always used Mobile 1 in all our cars/trucks

What do you drive and how long do you go between oil changes? 99% of the time Mobil 1 will do the job just fine unless you plan going 15k+ miles on an oil change.

People say Mobil 1 is bad because UOA results show high iron wear vs other synthetic oils. There's debate if these "wear numbers" really mean anything.

are you planning on sticking with the Ford recommended oil change intervals of 10k?

i dont. I change mine at 5k. It just makes me feel better. But then again, for 8 quarts i stick with motorcraft.
in the end, i probably still dont spend as much as if i bought 8 quarts of amsoil and only changed it 10k

ps. voted amsoil.
