What Oil is the best?

[LS2ner]

First, If this is a repost i dont care..

Anyways, I see commercials all the time about how this oil is used by NASCAR drivers and how this one is used by NHRA drivers etc. My question is, in your opinion, what's the best oil? Support your answer if you want!

[Homer Simpson]

um, i use mobil1 full synt.

Something about it sticking to metal better helping eliminate dry starts which is #1 cause of wear.

i believe thats why GM recommends Mobil1 for their corvettes because national average on mileage driven on a C5 was 6000miles a year? Sooo, they would rather let the oil stick to the matel internals than it fall into the oil pan when the car is sitting in the old man's garage for weeks. Heard about it from my GM tech from school.

try this trick:

Get a flat head screw driver. Get a thing of regular oil on the tip and try to hold it by pinching it. Chances are, you'll be holding it.

Now try it was syntethic. Chances are, it'll slip outta your fingers.

I tried it in automotive class and its true.

[LS2ner]

I also use Mobil 1 Full syn. I drive a Frontier, but want it to be in top shape ya know? What sparked this poll was a commercial for Valvoline i saw earlier claiming their synthetic was better than Mobil 1.

i use moblie1...

German Castrol 0w30 or Shell Rotella T 5w40 are all that I'll ever put in my motors as far as synthetics go. Castrol GTX is as good as it gets when it comes to dino oil, and its almost always on sale between Wal Mart, Autozone, and Advance.

Mobil 1 is shit, it used to be good but their standards have dropped through the basement in recent years. If you're going to use it, go for the high-mileage synthetic, its a lot more durable than the normal oil. The only thing worse than Mobil 1 is Royal Purple.

There have been a bunch of good threads on here about oil. Motul 8500 is great as is any Amsoil. I really wouldnt ask for oil advice on here, go to a track and see what the real racers are using. I doubt you'll hear many of them mention any positives about Mobil 1 other than that its cheap and readily available anywhere (so is the Rotella T).

Check out the Bob the Oil Guy website and if you're really worried about your oil send a sample to Blackstone Labs every few oil changes to see if your motor is still in tip top shape. There are a lot of test results on there, look them over and see if you still want to run Mobil 1, I dont. You want an oil that keeps its shear weight up over the entire lifespan of the oil, not Royal Purple which starts as a 5w30 and after 3K miles has a shear weight less than 20.

A better question would be, who is using good oil but running it through shoddy Fram filters? Napa Gold and Pureone are what I've used with great success.

My brother has always used Mobil1 in his ride and with almost 300,000 of rough driving and still kicking? i'm sold.

Any of you guys using royal purple ever send your oil out for analysis? I think if you did you would never touch the purple stuff again. That statistic is from a handful of subaru owners on nasioc as well as a handful of other car owners on Bobtheoilguy.com. I guess its good if you want to change it out every single track day (which you should do anyways) but for the long haul it breaks down very quickly.

At least Royal Purple doesnt burn multiple quarts of oil like Mobil 1 does on the majority of cars I've heard of people running it in.

Mobil1 hasn't sold full synthetic in nearly a decade, it's all a conventional synthetic blend

After Mobil1 sued Castrol for selling a Group III oil as full synthetic (Group IV) and lost they too begin producing the PAO crude oil based blend and selling it as fully synthetic. The Better Business Bureau declared since the oil has similar properties & performance they can call it full synthetic.

The catch is Mobil1 never told their customers yet continued to sell Group III oil at Group IV prices.

*NOTE*
I forgot to mention this ONLY applies to the US market, full synthetic in any other country are indeed fully synthetic.

I agree 100%. I will never run Mobile1 or Royal Purple here. Not sure if the Castrol or Havoline from Advance is any better but it has done us just fine. And as far as Fram filters go, they use to be a really good filter back in the day but I steered clear of them years ago when I had one collapse.

The only reason I offered my opinon is because we drive 200-300 miles a day and they are hard miles along with our drag racing hobby with several Nitrous applications and a few dozen Mustangs in the crowd. I am by far a professional but I will stick to what I said previously.

[Barefoot]

i use mobile 1 if i cant find royal purple.

Motul

[Total_Blender]

Rotella 15w-40 went into my 8v Jetta. Now that I have a Ford I use the regular Shell brand 10w-30. Bosch, Mahle, or Mann filters ONLY for the VW's, Motorcraft, Wix, or Napa Gold for the Fords.

On older engines I sometimes add a quart or two of ATF with the oil change to help with sticky lifters and such.

All 4 banger Hondas use the same oil filter at least up to the R series and K series i believe. They may have the same filter too

I have some royal purp(used) that i need to send in. I wanna kno wut my engine specs are...

[87 Turbo II]

I use the cheapest brand non synthetic 20W-50 at any given store I'm in. when I need oil, I need it then and there, and I buy what's available. My car's just gonna burn it anyways. Now all my oil filters are genuine Mazda OEM black filters.

[boosted b]

u fail

[87 Turbo II]

u fail

Nah, rotary engine, goes through oil like crazy, synthetics aren't designed to be burned, so they gunk up to stop leaks on cylinder walls, in a rotary, this gunk can build up lock the engine. I change the oil every 3K miles with a brand new filter, and whatever is on sale, bu tI'm constantly buying single quarts cause the oil gets burned up.

[SuperChicken]

A friend of mine is one of the better known race-bike engine builders around. He has told me that Royal Purple is great for freeing that last 1 or 2 horsepower in a racebike motor, but that it comes at the expense of replacing bottom end bearings 2x per season! Sorry, not for me! Mobil1 FTW...I've been running it exclusively in my '95 Nissan V6 pickup, which now has 245,000 miles on it bone stock. It just passed emissions the other day with a HUGE margin to spare.
I haven't changed the oil in my "new" Teg yet...

You missed a few.

Royal Purple
Redline
Elf (What Eurotrash like me SHOULD be using)
Pennzoil

I typically use Pennzoil when I can't get Elf, the tests are pretty similar between the two and the cost isn't that drastic. Ignore the BS commercials about ASE certified Mechanics use this, or more Nascar dipshits use that. It's all marketing. They use it cause they get it free most of the time.

I have used the Advanced Auto brand for probably 12 years and have several hard driven F-150's with 300k on them and a Silverado 4.3 with over 400k on it. I cold go on and on but you get the point.

I really don't think there is that huge of a difference as long as it is maintained properly. I know that I will never use Quaker State sludge mush again. Bought a truck with 60k on it and the guy swore by Quaker State and changed the oil every 2,500 miles. It ended up having an intake leak so we pulled it to put new gaskets on it and there was a 1/2 inch of Quaker Sludge in the valley.

[Tech5]

Advance Oil is Havoline! good oil!
