Full Synthetic Oil

[jegg]

I just got off the phone with a ford service advisor and talk to him about switching to full syn oil. He told me its not recommended by ford to switch to syn. wtf? why the hell not?.

Hmm.. that doesnt make much sense. Motocraft's 5w20 is a syn blend itself. Sounds like someone trying to scare you into buying their own products.

The reason why i called ford to ask was because i wanted to buy some Royal Purple and have ford switch them out on my next oil change. I would do it myself but i want to keep all records for service on file to keep my warranty in tact.

hahaha. dam my dealer told me go for it.. i wonder what was the reason behind it. i went from a badly treated 2000 GT vert and took it right into the garage and added mobil 5w30 and a K&N oil filter after a week of driving it around with what ever it had before. dam thing felt slippery and smooth. and now after a couple of oil changes and adding 50,000 miles to it i still use the same oil and filter. its currently at 74,000 as of this morning and im doing another oil chage this weekend. dont belive everything you hear take the info and do your own research.

they told you that because they want you to buy the motorcraft oil. the motorcraft oil isnt all that bad, however RP, M1, Redline, Amsoil are all better. when i worked at a dealer people would drop their car off and say they had already bought the oil and use what was on the backseat. the service writers didnt care and they just wrote that the customer supplied the oil.

He just said that it was not recommended, not that you couldn't use it. Any car (as long as it is not brand new) should be able to go ahead and go fully synthetic.

I have been running full synthetic, engine, trans, diff, brakes and engine since 1997 in my 1996 GT. All I can tell you is that it makes me feel real good, not sure of any performance improvments.
What made me make the change was my old beater had 300,000 miles on it before the timing chain finally broke. The mechanic who replace the timing chain said he had neevr seen such a clean engine inside with that kind of miles on it. My beater was once new to me and I had always used synthetic oil. Good enough for me.
On the current Stang I change to filter every 3000 miles followed by the oil and filter every 6000 miles.
Seems to work for me!!

Full synthetic oil is a designed to do what you’re doing with it; conventional oils are just making use of what you’ve got. A synthetic lube will keep you running longer and cleaner. Whoever recommended that for you either didn’t know, doesn’t care or wants to sell something.

i can tell ya my old 5.0 had a noisey (sticky) lifter - sounded like engine knock. i went to synthetic oil and my engine noise vanished. i'm sold on the stuff.

I run RP in the GT and M1 in the LX

I swear by the stuff, CHEAP insurance !!

 

[smokin'Red35th]

FORD service centers are very conservative! They don't want to recomend something and then have a motor with a problem...only by the book. Synthetic oil can be a problem with some motors as the oil is so thin (due to low viscosity and wetting ability) that it can seep into places and result in leaks.

I use synthetic (Mobil I) in all my cars, but it is really is not justified unless you plan on keeping the car for about 150k miles. Synthetics reduce engine wear thus result in extended engine life. Another benefit is increasing the length between oil changes. For me, this is a great time savor. In my Intrepid I change every 12,000 miles. the Mustang and Suburban, I change every 6,000 miles or twice per year (the stang I only put 10,000 per year on it). I drive 5,000 miles a month on the Intrepid, so this is why i go 12,000 miles.

just did my first synthetic oil change today on my 02 gt. when i brought the car in i was just going to do the normal change, when we drained the oil, (which was changed last by ford) it was really black and dirty. only put 1,500 miles on the car sience that oil change. i think that ford decided last time that my oil was clean and left it in there and charged me for it. i dont know how else it could get that black. when i saw that i got super pissed its not going back there, and me and my boy swaped to mobil 1 synthetic.

No offense, but this is simply another scare tactic. Did they tell you that they (Ford) had to change the oil to keep the warranty? I believe it, but that's crap! They would have to prove whatever damaged was caused by your lack of maintenance. Certainly having them handle all your oil changes and keeping all your records makes this easier, but this is not necessary. Again, the have to prove you are guilty, you don't have to prove you're innocent. This is an unlikely scenario anyway, but I do keep my own records of our oil changes and other maintenance. Our dealership has no problem with anything we've done, especially simple oil changes. They changed the harmonic balancer when a small oil leak developed around it on my wife's 01. At the time it had Nitto DRs, LCAs, C&L MAF, 4.10 gears, Tri-Ax shifter, very loud off-road exhaust with dumps. They didn't even blink. They know people are doing this to their Mustangs. We only take it to Ford when it's broke. Which, thankfully for us, hasn't been too often. But everytime, they've been great.

i was told that sometimes full synthetic oil makes your engione to leak oil especially if you have high miles

 

[Modular2v]

synthetics do not make your engine leak anymore than regualar dino oils would!!! They are the same thing except synthetics have longer lasting detergents and dont wear down as easy

Im planning to do my first oil change when the odometer hits 1200 miles. Is it a good idea to start using Mobil 1 early on? I was told that doing so, keeps the engine "new".

Not sure about Amsoil, but Redline is now available at Advance Auto stores.

Actually, an engine with more than 25k miles should stick to dino oil and not switch to full synthetic... an engine with high miles of dino oil usage will leak like badly on a switch to full synthetic - I have heard this many times over...

ford motorcraft synthetic blend is good enough for me... as long as you chage out your oil ever 3k it really doesn't matter that much...

buy a new car, brand new, switch to full synthetic if you want.. but stay on it... you can switch back to dino... but once on dino stay there...

I for one can't forsee an engine lasting much more than 150k miles with heavy track/street use anyhow.... especially blown or juiced...

IMHO!
