Whats the best syntheic oil out there

 

From everything I've seen and read - Mobil 1.

 

Quake State has 100000 miles more than moble



Sorry i did express things that well on this post, I had every off.

Here is what QS has that Moble dosn't...


Either when you purchase a Quaker StateĀ® oil change or change your own oil with Quaker StateĀ®, We will give you a FREE lubrication limited warranty that will protect all your engine's lubrication-related parts, such as the pistons, timing chain, valve stems and cam shafts, for 10 years or 250,000 miles.

How to get coverage.
To qualify for coverage all you have to do is get a Quaker StateĀ® oil change or change your oil with Quaker StateĀ®. Your engine must have less than 36,000 miles and have been manufactured within the last 48 months. It's that easy!

How to keep it.
Just get a Quaker StateĀ® oil change at a service center or change your oil with Quaker StateĀ® every 4,000 miles or 4 months, whichever comes first. This may not be the same as some vehicle manufacturers recommend, but neither is the length of our limited warranty. The oil filter and air cleaner elements must be replaced and the emission control system must be maintained in accordance with the vehicle manufacturer's recommendations. You have to take very good care of your engine if you want it to last for ten years. Or 250,000 miles. Our limited warranty is transferable. The Quaker State limited warranty offers something that could prove valuable if you sell your vehicle before it's gone 250,000 miles. The limited warranty can be transferred to the next owner.

 

who on this planet would even consider going 100000 miles between oil changes in their Mustang? Even with Synthetic, I would be nervous even going 5000.

 

Put it this way - NASCAR and IndyCars both use Mobil 1. Stands to reason that engineers for those engines aren't going to skimp on the oil. They need to squeeze every last bit of performance and reliability out of those engines...or else their cars won't have a chance of winning.

If it's good enough for a $500,000 IndyCar, it should be good enough for our Mustangs.

 

Hey thanks my Gt goes in next week for its first service and I will get a sample of the oil as a friend said that they can test it for what ever any particulates that someone may not tell an owner ? don't know why cause if its a warrenty issue the dealer still makes $$ on it ?

 

Does Mobile1 synthetic come in 5-20 weight?

 

Yep, sure does. Have it in my 05 right now.

 

This question is like asking 'what's the best beer?'

Having said that, my 2 cents- I run Valvoline dino oil in every non-marine motor I own and have for years. I try to keep changes to 3K miles or less on my trucks/cars. So far, this has worked for me.
But I'm thinking of taking the leap to synthetic blend oil - what's the word on that stuff? Is there a benefit or is it just marketing to those who want something better than dino, but are too cheap to buy pure synthetic?

Any SAE 5W20 synthetic that meets Ford's WSS-M2C930-A spec will do just fine. My personal preference is Mobil 1.

 

All of the extended mileage oils say to be changed every 6 months - just like all the other oils out there. They are really designed for people who put a lot of mileage on their cars in a short period, but don't want to change their oil every month.

 

The magazine Grassroots Motorsports did a write up a couple of months ago. They said barring a special blend for racing Mobil 1 gives you almost as good as a custom blendl.

 

Mobil 1 fo sho

 

Before someone else throws out the AMSOIL name, I will.

I have seen extensive studies on synthetics.

AMSOIL and MOBIL 1 are to close to call.

An 18,000 mile study was done by independant testing and both oils held up very nicely.

The only difference of note was the AMSOIL viscosity was elevated.

My choice. MOBIL 1 hands down.

I have been using it for about 12 years or so and AMSOIL is not API (American Petroleum Institute) certified. If something happens to your engine and they can prove that there was a non-API oil in it, your screwed.

Brad, make the jump to full synthetic. A blend is a blend is a blend. You might as well stay with dino.

 

Um, where did you hear Amsoil is not API Certified? You need to read-up more before posting invalid info. Here's a quote, direcly from Amsoil.com
AMSOIL, the leader in automotive synthetic lubrication, produced the worldā€™s first API qualified synthetic motor oil back in 1972. Trust the extensive experience of AMSOIL, The First in SyntheticsĀ®, to do the best job protecting your vehicle.

Amsoil is definitely API certified, it says it all over the bottle and all over the website.

Mobil 1 is very good oil. I have read that test where Mobil 1 and Amsoil were compared, and the Amsoil did have elevated viscosity readings. However, during that test, the car with Mobil one had six and a half quarts of oil added to it as well as a filter change during the test, where the Amsoil car only had 4 quarts added and no filter change. I don't plan on going anywhere near 18 thousand miles between oil changes anyway.

All the other tests I have read said that Amsoil beats Mobil 1. Do a Google search on the subject, there will be hundreds of responses claiming this. I would think Mobil 1 would sue Amsoil for false advertising if this wasn't true.

Supposedly, Royal Purple claimed they were better than Amsoil. Amsoil took them to court and won. Just what I heard.

Either way, I think either Amsoil or Mobil 1 full synthetic would be the best oils, but I'm going to keep using Amsoil. Been using it in the racebikes for years with no problems.

 

Can't go wrong with either one. Mobile 1 is just alot easier to find.

 

RP is my preferred oil, granted it's hard to compete with a marketing machine like Mobil. Anyway if you want more info look here: RP

 

Motul 8100 series, without a doubt.


PS - if you need any convincing, maybe this will help:

 

What mileage are you all changing over to synthetic?
