Motor Oil....What Kind??

[Seraphitia102]

Sorry!
I did actually search, but didnt find exactly what I was looking for. Believe me, in the old forum I belonged to with my other car, I got sick of seeing new people ask the SAME questions over and over. So I know how you feel. I'll try harder not to repost stuff next time! By the way, if this question comes up a lot, why not add it into one of those FAQ sticky posts?? Just a thought.


Anyway, thanks for the help once again. I've also heard dont use synthetic right from the start. Cant find anything to back that up, but I know I've heard it before. I'll probably go with regular oil for the 1200 mile change, then switch to synthetic at the 3000 mile mark.

Myth
"You should break in your engine with conventional oil, then switch to Mobil 1.

Fact
You can start using Mobil 1 with SuperSyn™ in new vehicles at any time, even in brand-new vehicles. In fact, Mobil 1 with SuperSyn™ is original equipment (it is installed at the factory) in:


Chevrolet Corvette
All Porsche vehicles
Mercedes-Benz AMG vehicles
Dodge Viper
Ford Mustang Cobra R
All Aston Martin cars

One of the myths that persists about Mobil 1 is that new engines require a break-in period with conventional oil. Current engine manufacturing technology does not require this break-in period. As indicated by the decisions of the engineers who design these high-performance cars, Mobil 1 with SuperSyn™ can be used in an engine from the day you drive the car off the showroom floor.

Royal Purple's site says this:

Can I put Royal Purple® into my brand new car?

Yes. Royal Purple® currently offers many viscosity grades of API Licensed Motor Oils. (See the Royal Purple® Motor Oil Product Page or visit the API Engine Oil Licensing and Certification Website for more information). To allow for proper break in of the engine, Royal Purple® recommends waiting until the manufacturer's first scheduled oil change or a minimum of 2,000 miles in new gasoline engines. Allow 8,000 to 10,000 miles before using Royal Purple® in diesel engines.

Hey man, I did not mean to be offensive at all with my comment, I was trying to add humor to this "great debate" on every site I have visited. I appreciate everyone’s oil opinion and do read them all with interest.

As far as using Synthetic right from the start . . . well, that is one debated subject also. I always heard that the engines that had full Synthetic from the factory had dyno time first, may be a myth there too.

I gain my Synthetic use belief from racing 2-stroke engines. Although not the same for sure but the cylinders do get oiled from the mix. The wear is so great on the high reving 2-strokes I would change pistons and rings 1 or 2 times a weekend on occasions and found if I used Synthetic oil to seat in the new parts I would get a lot of blow by past the rings. So I had to have a dino oil mix just for seating in the rings.

I also found that the high wear rate of 2-stroke engines was reduced an incredible amount when I started using full synthetic oils. In the days before I switched to synthetics I was lucky to get a ring to last a couple of heat races and they would need changed after an hour long race. That time was at least tripled and sometimes more after the switch to Synthetic.

Now back to our Mustangs . . . I changed my oil often in my new Mach, I drove it home from the dealer and changed it then even. I found lots of metal too. I changed again at 250 then 500, 1000, and at 2500. I used the 5w20 Motorcraft blend recommened in the manual until the 2500 mark then made the switch to the Motorcraft full Synthetic 5w20. I have always followed a similar cycle of oil changes at break-in time with new cars and have never had a compression or oil usage problem in any of those engines.

My Son bought a '04 GT like you and he followed the same cycle and switched to Motorcraft 5w20 full Synthetic at 2500 miles. He couldn't be happier either with the way his Mustangs runs.

Oh yea, Welcome and good luck with your new GT.

Thanks for the help guys. I'll definitely change it out at 1200 miles. I still havent really decided which oil to go with, but I'll probably go with one of the ones mentioned............Mobil1, Amsoil, or Motorcraft. A friend suggested I go with Royal Purple full synthetic. Anyone ever use that, or have any experience with it??

I Use Royal Purple 5W30 with a K&N Oil Filter and love it. I have had it in for about 3500 miles and plan on changing it @ 6000. It has 400% greater film strength to reduce breakdown, and increases HP and fuel economy. Can't go wrong with this oil.

Because unfortunately, this is a never-ending debate! Half the people are all for synthetics and swear by them, while the other half think that for the most part, it’s just snake oil and have no real use for them. I for one, think synthetic oil in an engine is an unnecessary added expense for your everyday average car and really isn't warranted unless you live in an area where the vehicle will see extremely high or low temperatures. But hey, that’s just my opinion! I base it on the fact that there are hundreds of thousands of vehicles on the road with 300-400K on them still ticking after running nothing but Dino oil all of their lives.

Others, like some who have posted in this thread feel differently and won't run anything else based on the oil manufactures claims of added protection and *snicker* horsepower. So…..pretty much anyone’s opinion going to be just that…their opinion. Until it's widely documented and proven beyond a shadow of a doubt that an engine will last any longer or perform any better with synthetics (in the real world, not just a controlled lab testing) it’s just going to be one endless unproven argument back and forth between the two groups.

Hense…..no sticky.

i recently just switched to Synth....I did it cuz of the longer change intervals...and supposed better protection. Price wise---its no big deal because the longer intervals make up for the added expense. i made the mistake of buying a mobil 1 filter first time....but now will just get Moto or Purolator and change them every 3-5 thousand and just top off the oil...

If an oil meets the spec in your owners manual,it is OK to use in your engine. Manufacturers do a great deal of expensive oil testing to establish what it will take to properly lubricate a given product. Naturally, many owners assume a synthetic has to be "better" in some way. It may be, but much of an oil's performance is in it's additive package. Therefore, rather than get into wether a synthetic might or might not be better than a well-formulated petroleum oil, the best advice is to stick to the spec in the owner's manual, wether that be Dino oil or synthetic SG, SF or whatever.

hotrodnut,
I know you werent trying to offend me. I was just joking with you. Thanks for the info.

gearbanger,
Very valid points. I guess I should just do the easy thing and use what the manual says for now.



Thanks again!

I like using synthetic oil in all my newer vehicles. I'm just wandering about this post because I heard someone say that "It might be better to use a little heavier oil than the 5w-20 Ford calls for because the vehicle manufacturor's won't make much of a profit if a vehicle last longer than 100,000 miles." I thought this was crazy when I heard it. I was just wandering what you guys thought about it.
I heard it when I was in line at Autozone buying my 5w-20 Castrol Syntec. It was one of the workers behind the counter. I've noticed that they hire almost anybody now to work there. HaHa

i use 5w30 in my stang cause its a 98 and in my grand marquis cause its a 00 and when they were new ford called for a 5w30 weight. in 2001 i was told that my vehicle was actually designed for 5w20. besides there are no internal differences in the motors like some dealers say there are. and 5w30 is much easier to acquire than 0w30 or 0w20 in the mobil 1 flavor, i like less than a mile from a costco that sells 6 packs for $23.
