Important Information About Mobil 1 Synthetic Motor Oil For Mach 1's
 
Hey I just wanted to let you all know I called Mobil 1 today and spoke to them about the difference in 0w-20 and 5w-20 Mobil 1 synthetic oil since 0w-20 says on the bottle it is recommended for ford vehicles that would otherwise use 5w-20

Well, they told me that 5w-20 IS NOT just 0w-20 packaged in a different bottle as many have stated on this forum. Actually 0w-20 is being discontinued because many consumers were having trouble at the dealerships for not using 5w-20. He told me that 5w-20 would replace 0w-20 and it is actually a little bit thicker viscosity at start up than 0w-20, but would supply all the same benefits gains from 0w-20. He said those individuals using 0w-20 could change to the new 5w-20 without any difficulties.


I think this is some important information for fellow mach 1 owners that are currently using either 0w-20 or 5w-20, so i just thought i'd pass the word along.

Thanks - I'll get mine changed to the 5W-20 at the next service (will be before weather gets warm, so I doubt if the lower viscosity is an issue right now).

I agree. The 0w20 meets or exceeds the Ford spec. Seems fishy. But I dont doubt 99GTCONV. I was wondering why the cases of 0w20 were so cheap at Wally world.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 
I just checked Mobil1's website and there is no sign of 0w20 anymore.

It meets or exceeds specs, but the language used by Ford states that all of their newer gas motors should run 5w20 or risk voiding the warranty. I personally think that it could be challenged, but I wouldn't want to go through the trouble of finding out.

I agree, it's just not worth it. I'll be changing mine back next go around. Thanks for the info! :yeh:

Thanks for the info!!!

I have done 2 oil changes on my mach since I got it and I have never poured such a thin oil in a performance motor.

The last one I did i switched back to 5w20 dino oil from ford.

What about 5w30 ??? anybody using it?

I wouldn't use the 5w30. The reason Ford says 5w20 is to get oil to the cam journals quickly, also the thinner weight oil will delay lifter pump up (i.e. valve float as a result). I doubt anyone will reach the rpm it takes to bring on float with 5w30 though. I think around 7000rpms. Just use what Ford recommends to be safe. Btw, no problems using 0w20 here. Same protection on these close tolerance engines. It's not like the old days. Besides, on startup, I want oil to get to every part of engine as quickly as possible to prevent wear, which in turn, will increase tolerances.

Leave it to Ford. I'm starting to think they pay people just to find ways to void the warranties. What's next? If it isn't Ford's oil and they didn't change it the warranty is void? I've always run a better grade of oil and changed it more frequently than what the manufacturer calls for. I want the added protection.

I'd say it is "also" has a lot to do with marketing and brand recognition.
Sales down Mobil?? Just think people go in ask for 5w20 Mobil, "Well miss/sir Mobil does not make a 5w20 they make a 0w........ That is all most people have to hear to go purchase some other brand. 0w what! does not even make sense. :notsure: I am sure in olil terms it does but not to joe public.

Like this post mentions, I am not disputing that it is a rebranded oil, but I am sure that marketing had lots of influence.

I completely agree with you DanK. But what now? how many cases of 0w20 do you have stashed? I only have 2 left. :yeh:

UNFORTUNATELY, none. I guess I need to run down to Advance auto parts to pick some up, if they still have it. Not even Wal Mart has it here, never did. The 0w20 was already difficult to find for me.

I bought mine from Pep Boys. They offered me a Pep Boys Calender for $1.00, I said no thanks. Then she pointed out that they have a coupon in the calender for Mobile 1 oil so I bought the calender. Ended up getting a case (6 bottles) for only $16, normally $31! I couldn't complain.

anyone who uses 5w-20 is asking for engine trouble. 5w-30 is the way to go

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 
that's an obvious misinformed statement since you don't own a MACH 1 because the recommended oil weight by Ford for our cars is 5w-20 not 5w-30. By going to 5w-30 why it may not hurt the engine, it will lessen performance and fuel economy and risk voiding Ford factory warranty from some dealers as it is not the recommended equipment.

Another reason Ford says to use 5w20 is so oil reaches the cam journals quickly. The tolerances are tight on those journals. Do what you want though.

someone let me know something when i brought my car to ford they told me flat out that running a full synthetic in the mach is not a good idea is this true or was he bs me.so i have fords oil in it as of now which i beleive is partially synthetic.should i change it to full or not

They were somewhat right. Until the engine is broken in, you don't want to use a full synthetic. It will prevent the engine for breaking in properly, it won't let it wear. By your second oil change you should be broke in and ready for full synthetic. Some even recommend not changing over till 10,000 miles.

If the syn oils stop engine break in, why do high end cars come from the factory with syn oils ie: Mercedes, Ferrari, Corvettte, Viper ? Would'nt the syn oils stop them from breaking in also?

Just wondering....

The tolerances on those cars are super precise and dont need much "break in". Also, all manufacturers "break in" the engines during the preinstall run. Trust, me.....They drive it like they stole it before it ever gets put in the car. :yeh:

Ah...true on the vette's, vipers etc... the engines are "seated" at the factory, that is why they can run full synthetic. On the Ford oil....to save your butt in a warranty scuffle, it is better to use what they say...try going and buying a new engine on your nickle right now.... and these engines are very close tolerance, hence the 5W-20W synthetic blend...remember aluminum grows as it gets hot, and to use a higher viscosity oil is only going to hurt it. The guys and girls who design these high horsepower engines are no dummies, I am sure they destroyed quite a few during tests.

I left regular oil in for 4000 miles then switched over to the regular RP which is not fully synthetic from what ive been hearing, more like a blend

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 
When I dynoed the Mach the owner of the shop with a WS6 told me that he usually sees the LS1 Fbodies putting out more RWHP than the full syn C5's. He claimed that the vette motor never gets a chance to seat properly. Who knows but I can say that it's slick compare to regular oils. I picked up 1mpg more when I use Moble 1.
