What do you guys think the best oil is for my 00 GT V8?

 

Depends on how much cash you want to spend. If you're rich, go with Redline 5W-20 or 5W-30. If you want something cheap, Mobil Clean 5,000 is also good. In the middle, you have Mobil 1 and Royal Purple.

 

What do you think of Quaker State. I used it in my other cars but now this is a Mustang big difference. I am definitely not rich.

 

full synthetic FTW.

 

I've heard that synthetic oil is only good for cars with leaks or lots of miles. I've only got 40000 on 2000.

 

not true, mines got 30k miles and ive always used fully synthetic.. exspensive but good, Mobil 1 5w 20 FTW!! but once you go synthetic theres no going back to regular oil remeber!

 

Thanks I'll remember that. Like your Mustang

 

Disregard anything you hear about synthetics. They came out and everyone went ga-ga over them, then they all figured out it was just oil and the ga-ga faded, now there's more BS in peoples heads about synthetic than there is fact.

Fact: Synthetic is good lubricant. As good or a little better than conventional.
Fact: Synthetic is expensive.
Fact: You don't need it but there's no bad time to start using it.
Fact: There's no problem mixing synthetic with conventional or vice versa.

Repair is good for cars with leaks and a rebuild is good for cars with high miles. Heavier viscosity oils are typically a little better in really high mileage cars as the clearances have grown a bit by then and the thicker oil will help to keep oil pressures up and films adhering. Use the thinnest oil your car was designed to operate on given your use case. You'll make more power and you won't run the pressure through the roof.

If you really want to spend 6 bucks a quart (36 bucks a change for V8 cars) then use any of the high quality oils from:
Royal Purple
RedLine
Amsoil
Mobil 1
Castrol Syntec
Quaker State Full Synthetic
etc...

 

nice ride

 

Royal Purple 5w20 FTW!

 

lol, I was getting an oil change done for my mom at a local shop and inquired how much it would be to change the oil in MY car with full synthetic... he quoted me 75 dollars! and that was for only 5 quarts... We take 6 ff I am not mistaken... hahaha, I laughed and took my moms car and went home and did my own oil change for ~30 (mobil 1 full syn 5w20)

 

im at 56,000 miles..using Mobil 1 5W-30 Synthetic.

 

The best oil, is usually the cleanest, as clean mineral based oil is better than dirty synthetic. Having said that, the cleaner you can keep you oil, the better it is for your engine or whatever your lubricating.

Lots of factors are at play with oil, like drive cycle, load, temps, turbo, etc. The factor that is overlooked is filtration. If you can improve the filter, the oil can do the best job for you.

I have used magnetic filters to improve filtration. How you go about it differs, but there are a few out there that will do the trick. Ford offers a pretty good in-line filter. It is labeled for transmission, but it works well in any application with a cooler line. XC3Z-7B155-BA is the part number. You might also check Emerging Enterprises or Boss Products for what they have to offer.

As a side benefit, if you filter your oil better, you can use it longer. Extending the drain interval will save you a few bucks each year.

Something to think about.

I hope this helps.

 

Has anyone ever tried Duralube oil treatment? I tried it once but it was in a 4 banger so I couldn't really tell if it made a difference.

 

You wouldn't happen to know the price of the filter. It's getting close to my first oil change. I'm going with half synthetic oil probably Quaker State. Used it all my life have had good results so far.

 

I think you should probably go full synthetic or full standard. Mixing isn't that bad but different oils wind up with different viscosities so I would be cautious about doing half and half. R3dn3ck, what is your take on that?

Filters are only like 7 or 8 bucks (I've even seen them down to 4 or 5 from different stores) depending on who you go with. Fram makes a good easy grip one which I am happy with.

 

You can buy half synthetic oil.

 

I hate fram filters. There's nothing quite as skimpily made.

Synthetic blends are good. They meet or exceed specs and I've always gotten good results from them (as good as conventional oil anyway).

Mixing oils outright like 3qts of this conventional and 3qts of some synthetic is just rice. It's stupid and wasteful of synthetic oil. Factory synthetic blends have guys with phd's figuring out the recipe for. Joe Sixpack mixing syntec and pennzoil in his driveway doesn't quite measure up.

 

My mistake. I remember the synthetic blends. My brain isn't operating today!

 

Yeah like he said I meant synthetic blends.
