I am running synthetic blend on my 04. I am using it just an everyday driver and all I have done to it is 18 inch wheels, superchip, and dual exhaust. I am planning on doing an under drive pulley, new gears in the rear, and a C.A.I. in the future. If I upgrade to full synthetic will it make a difference and how does it help the engine?

its not gonna make a noticeable difference in power

[MWWarlord]

+1 it isn't gonna help with power. What it will do is significantly increase the life of your engine. So it is a good investment.

A friend of mine who is a highly recognized mechanic here in town was telling me about synthetics. We were talking about this same topic and he was telling me that no matter what oil you use, as long as you change it when needed and tune ups when needed, your car will run fine. But also that synthetic's will not allow your piston rings to seal properly. And eventually it'll start smoking because of burning oill due to the rings. He has an old boss which he drives to work and maintains on a very high level and a lightning that runs low 13's. So being a well known mechanic for many years and so much background with cars, particularly fords, so I'm pretty sure he knows what he's talking about. Yeah I know fords has nothing to do with it, just wanted to throw it in.

I tend to agree with this for the most part. It is claimed that synthetic oils should not be used on a new or rebuilt engine since it slows ring seating. The ring seating process is a mystery to me. If the cylinder walls are within specifications and have the correct finish, the rings should work fine, but the story is that they need to wear a little bit to seal. Synthetic oils are supposed to not allow the initial wear to seat the rings. Conventional oils are adequate as far as providing lubrication and the important thing is to change the oil regularly since it removes suspended carbon and other contaminents. I think you can use either one after the engine is broken in and the synthetics are supposed to lubricate a bit better and also are claimed to be more heat resistant. Personally I use 5W30 Castrol conventional oil and have never seen any abnormal wear with it.

Yeah so I think my engine has had plenty of miles and abuse to get those rings seated properly, dynoing it tomorrow, so today picked up some royal purple 5w20 engine oil. Trying to free up as much power as possible. Did you guys catch that one show on the spike channel that comes on like saturday or sunday mornings where the guys changed all the fluids (oil, transmisson, and rear end) to royal purple and got like a 5 hp increase. Pretty impressive showing how much resistance and friction the royal purple line of fluids can take away.

+1.....yeah breakin in an engine with synthetic is bad.....but once its broken in run full synthetic and itll last a lot longer.

u realize 95% of new Sports vehicles are shipped with synth. and broken in with it. So it must be ok.

[moond0ggie]

The synthetics hold up better on extreme duty engines, those that operate in the higher 6,000 to 10,000 RPM range for extended periods.

Also very helpful in extending engine life on $60K to $100K+ exotics,

I wouldn't bother with it in my DD except maybe s/c.

[shadow5403]

i dunnno....i have read what the others have about the rings not seating correctly, so i dunno?

[scubasteve041186]

um desiel trucks were better off with synthetics from what i was told. and they don't go into the high rpm but they do get worked

that is VERY FALSE
if you change your oil when you suppose to and maintain your engine then you should not have engine problems OIL RELATED

this has already been debated before but that statment in itself is FALSE
although synthetic oil is IN A WAY somewhat better. that does not mean it will pro-long engine life!
try running it for 30,000miles and see how good it is

[GreenFaleen]

the only difference between synthetic and convential is synthetic is made with a man made base instead of dead dinosaurs

a synthetic will hold its viscosity through temperature changes where a conventional oil will vary a little between hot and cold, also a synthetic will leave less deposities since it doesnt break down as quickly,
a conventional is better to use when breaking in a new engine mainly because it is easier for the rings and seals to absorb

Hey Man I'm just saying what several mechanics have told me. BTW this post is OLD!!!

ok im not talking from tire kingdom knowledge
im telling you FACTS not a mechanic trying to make more money off you

this is from PERSONAL experience and knowledge and also backed up with a MASTER TECH ASE CERTIFIED TECH

i should taken pics while i had the chance of the proof.

[Hourofpain]

end this fucking thread

yes synthetic is a little better

regualr oil is just fine too if you take care of it properly

/END!

[MWWarlord]

Chill Chris...I'm not arguing with you. I was just saying where I heard it. I'm sure you're right...ok.

[itschristorres8]

im not trying to argue either im making a point

[Replica R]

Don't get angry remember woo-sa, woo-sa
