Oil Type-5W-20-Do you run regular oil or do they make a synthetic?

[Disneyfun1]

As I am pondering whether or not to get one-if i can-i saw that it takes 5W-20 oil, like the new GT's say. Do you have to go to the dealer and get it, i have not seen that one in the store yet, or do they make a mobil 1 synthetic, or do you even want synthetic??

as for me pondering.....i know i want one. I have located a couple dealers that are allocated 1 each who have no names on them and can still get what they want on them-hopefully!! they question is to pay 29,000 for it and have high payments, or just get a GT for 22,700, and have the payments lower. I am still working on getting the mach-I hope!!

Wal-Mart carries the 5W-20, Motorcraft synthetic blend for $1.77 a quart.

I currently own a 2001 GT I love this car but if you can swing it, the Mach will be an unbeleivable ride.

Good luck on your decision, mine was easy MACH all the way!!

The Motorcraft 5W20 is a synthetic blend. It is a good quality oil and I found it at my local independent auto parts store. However,after I put 5000 miles on my Bullitt,I switched to Mobil 1 5W30 synthetic for a little higher temp protection.

[Disneyfun1]

Since i live here in Phoenix, AZ, i will definately want high temp protection!! In the summer, its over 100 degrees for something like 70 straight days. Am i going to want to switch to mobil 1 5W-30 for either the GT or Mach1? Or should i do as recommended and use 5W-20 only??

[BFVTHOKIE]

It's based on API grades. Amsoil sells 5w-20 as well, and there 0w-30 will work in a 5w-20 engine just fine.

[Tomcat427]

Get the Mach 1 if you can swing it! If you can't then get the GT.

[Tomcat427]

If you want to keep the Chrome Yellow V6 supercharge it and you will be close to the V8.

Isn't it great to have so many options with the modern day Mustang!

[gotmach]

synthetic oil has been proven by Mustangs and Fast Fords to provide 5 hp gain. Its a plus keeping the drivetrain oiled up on cold starts and in boiling in hot temps. Take a quart of 5/30 synthetic and 5/30 regular oil and put them in the freezer overnite and try to pour them out the next morning.. the synthtic will pour! IN my opinion castrol 5/50 has the best full synthetic that covers all the cold and hot temps. Yes synthetic oil cost more , but isnt your Mach worth it?:THUMBSUP:

I got this information off the AMSOIL web site, and it is true across the board. I plan on switching to Mobil 1 5w-30 at my first oil change.

New for model year 2001 and Newer: Ford and Honda specify 5W-20 motor oil for most all cars and light trucks.

Here are the facts behind 5W-20:

Question: My owners manual species 5W-20 oil. Do I really need to use 5W-20 oil and why did my 2000 model year vehicle require a 5W-30 oil, while the exact same engine in my 2001, 2002 and newer engines "requires" a 5W-20 oil?

Answer: You do not need to use a 5W-20 oil. Do not let your dealer scare you by telling you that you have to use it for your warranty. That is a tactic that some dealerships use to scare customers. Once you know the facts and the Federal Magnusson Moss Act law you will be much better informed to protect your rights and use the type of oil you want to use.

One of the main reasons 5W-20 was specified for your engine is to increase the CAFE (Corporate Average Fuel Economy) reported to the Federal Government. CAFE is the combined average fuel economy of all of a vehicle manufacturers product line. Minimum CAFE levels are specified by the Federal Government. In order for a vehicle manufacturer to continue selling profitable large trucks and SUV's, which typically have poor fuel mileage ratings, as compared to smaller cars, and still meet mandated CAFE requirements, they must also sell enough of the smaller cars which have much better fuel economy ratings to offset the poor fuel economy ratings of the larger vehicles. For model year 2001, the change to a 5W-20 oil will allow Ford and Honda's overall CAFE to increase by a very small amount, typically in the tenths of a mile per gallon range. 5W-20 oil is a lighter viscosity than a 5W-30 oil and therefore has less internal engine frictional losses, or less drag on the crankshaft, pistons and valvetrain, which in turn promotes increased fuel economy. This increased fuel economy is virtually undetectable to the average motorist without the use of specialized engine monitoring and testing equipment under strictly controlled test track driving when compared to a 5W-30, 10W-30 or a 0W-30 viscosity motor oil.

Question: Could using a 5W-30, 10W-30, 0W-30 or even a 10W-40 or 20W-50, oil in my vehicle which specifies a 5W-20 oil void my new car warranty?

Answer: Absolutely not. Vehicle manufacturers only recommend using motor oils meeting certain viscosity grades and American Petroleum Institute service requirements. Whether a motor oil is a 5W-20, 5W-30, 10W-30, 0W-30, 10W-40 or 20W-50 (for racing and high performance applications in, for example, a Cobra R Mustang) or even a synthetic vs. a petroleum based oil will not affect warranty coverage. The manufacturer is required by Federal Law to cover all equipment failures it would normally cover as long as the oil meets API service requirements and specifications and was not the cause of failure. In addition, the Federally mandated Magnuson - Moss Act states that a manufacturer may not require a specific brand or type of aftermarket product unless it is provided free of charge. If your dealership continues to tell you that you must use 5W-20 motor oil and or/ a specific brand of 5W-20 motor oil, then ask them to put it in writing. Their position is inaccurate, and, in fact violates existing law.*

Additionally, if there is ever a question of whether or not a particular motor oil was the cause of an engine failure make sure to get a sample of the used oil in a clean bottle, typically 6 oz. minimum. The oil can then be sent to two independent testing labs for analysis. This is standard procedure for most commercial vehicles, trucking, construction/excavation and fleet companies and there are numerous certified test labs all over the country. Remember, a knowledgeable and informed consumer is your best defense against being taken advantage of by a car dealership service center.

Sticker in the engine bay says NO synthetic oil.

[POLSMACH03]

what does the manual say??

[TRMach1]

Here's what the manual says on page 199. Seems to be somewhat ambiguous to post a "no synthetic oils" sticker in the engine compartment and recommend a Motorcraft synthetic blend oil in the owners manual.

[03elanor]

No Synthetic Where is the sticker? I will be looking for it when the Mach 1 finally gets here.

[Twister Special]

This is confusing! 20w oil was usually for cold weather and 30w on up was for hot weather. When the multi viscosity came out was 10w-40, to be used year round. Then 10w-30 was supposed to be better than the 10w-40. Then in later years went to the 5w- 30 and 20w-50 for racing etc. Now a 5w-20. This looks like it would be to light of oil for summer use. Back in the turbo days they came out with a 10w-30 Turbo oil. It has an added heat additive because of turbo's being oil cooled. I have been using this in my vehicles since. I've been with the first generation of stangs all these years and this is my first new one in a long time. I had figured on using the 10w-30 turbo oil in this new mach 1. Of course I'll talk to my local Ford techs. The opinions on this site will be taken into consideration also.

[34Ford]

Ya gotta be careful here. A "synthetic blend" is NOT totally a synthetic oil.

Its a semi-synthetic oil.

The sticker said to use a semi-synthetic, which means you can use a synthetic blend.

Synthetic oil is what it says it is. Usually the price gives it away.

[FordFanForever]

Yes mobil1 does make a 5w 20 synthetic. I use it in my girlfriends focus.

[34Ford]

Okay here it is. Motorcrafts 3 types of oil.

1. SAE 5W-20 Premium Synthetic Blend Motor Oil
(which btw, is what the Mach 1 calls for)

2. SAE SAE 5W-30 and SAE 10W-30 Super Premium Motor Oil

3. SAE 5W-30 Full Synthetic Motor Oil

Who knows why they said semi-synthetic on the windshield and synthetic blend in the owners manual. Their the same.

So if the manual says NO synthetic, then dont buy the full synthetic. The price of it alone tells you the difference between the blend and the full synthetic.

Heres the Motorcraft oil.

[70Mach03]

Does anyone know what type was put in at the factory? Everything I've heard says to use regular oil during break-in then, if you want switch to a synthetic or blend. So, you would think Ford would use the regular oil at the factory.

[Mach__1__03]

Check this web page out.... now remember before you read this... be openminded.... It is on the AMSOIL webpage... so I am sure they are a little biased... I prefer to only accept independant testing(not paid for by either company, and not advertising for just one brand Oil.....

This is a test of a "near" weight oil... 5W-30 and if all said is true I would consider the AMSOIL ... Now I just wrote MOBIL 1 an email asking them to explain the web page in their own terms(because I have always used Mobil 1) when I get a reply I will post it..

I didn't know that Mobile1 made a 5W-20 syn. Last time I checked their site they didn't have it listed for their synthetics.

[Mach__1__03]

Ok I just found some more answers to the 5w-20 questions...

It is a long article but IT IS GOOD... and explains why ford has been making the oil requirements thinner and thinner.... explains alot and they seem very confident.

AMSOIL -vs- MOBIL 1 5w-30

Here's the real deal. You could spend hours on end trying to find the best motor oil and whatnot, and the simple truth is, if you take care of your car and use it like a normal car and change the oil regularly when you're supposed to, it doesn't matter what brand you use.

Just take the Amsoil vs. Mobil test as a perfect example. "Pour Point" is one of their tests. They claim Amsoil is better than Mobil 1 because Amsoil stops flowing at -60 degrees F, while Mobil 1 stops at -54 F. They take these tests to the ridiculous extreme, because no one is going to come close to those temperatures, and if you happenen to live in the Yukon, the last thing you'll be doing is driving a Mustang. All brands that are API certified are perfectly fine.

[funk]

I use conventional oil until I hit 5000 miles and then I change to 5w-30 full synthetic . This a very good article about the oil. It cost more, but I love my cars.Motul

[Mustang Matt]

here's a good thread about synthetic oils

syn oil comparison

[Tomcat427]

So what are you using?


I am still on the Ford 5w-20 until my next oil change. 1000 miles to go so I need a plan.

The SERIES 2000 - SAE 0W-30 Synthetic Motor Oil or their 5W-20 XL-7500 Synthetic Motor Oil looks promising. Price is a little more but I am only looking at changing the oil every 6 months. (Will be less than 3000 miles, it is truly a weekend car now.)
