Got 1300 miles on her now and wanna start driving a little harder now that the chip is supposed to be here today. I want to change the oil and realize that the factory calls for 5W-20.

Has anyone seen any downside to this, valve noise, etc.?

 

Corner:

My knowledge on synthetics is limited, but I do know you don't want to run it before the vehicle is completely broken in. Probably 5000 miles and beyond.

BTW, have you priced the synthetic. Ouch....

Anybody?

 

I put Mobil 1 5w 30 in my 96 Cobra on the first oil change and havn't had any trouble at all with it. I now have about 150,000 miles on it and it still runs like new. I think the whole "don't use synthetic on the break in" is an urban legend. I changed the 5w 20 in my 01 L out not too long ago and went with 5w 30 Mobil 1, and haven't had any problems there either. Just my $.02

Later,
Roger

At 1500 miles I had the dealer change my oil to get out all the nasty stuff that comes out the first time. I then changed it myself at 3000 using Mobil 1. It's now got almost 11k on it (coming up on my 12k oil change). No problems whatsoever.

Thanks guys. I ran synthetic in my '99 Cobra and will never use anything but synthetic from now on. Looks like I'm heading to Wal-Mart tonight.

Ouch??? This **** is cheap insurance. It'll go 10k to 20k between oil changes and STILL have better ratings than 1k miles of dino oil. If you have bought an expensive *** truck that burns more fuel than a Diablo and are yacking about putting in the best protection, then you need to rethink yourself and go trade it in immediately on a Jetta.

Fill your engine up anytime you want.

I'd like to start guessing what BfB stands for....

Didn't realize oil was such an emotional subject...

Corner:
Here's a good article.

Oh, yeah, BfB.
I don't think I have to rethink anything. Thanks for the observation, though. I'm sure everyone enjoyed it....

Not to start a war or anything but the basis of my quesion was really ther temperature range. Both 5W20 and 5W30 are 5 weight oils. Being down here in the hot humid south I don't think that the 5W20 has the temperature range of the 5W30. It routinly gets well over 100 degrees with high humidity here and I want as much protection as possible. That's all.

Whereas regular oil is parafin based and will cook at high temp and turn into a paste; Mobil one is not and will not breakdown like regular oil does. Remember the mobil 1 commercial where they cooked both mobil 1 and a regular oil on the stove. The mobil 1 stayed the same and the regular oil turned into a black grease.

In short, there is no down side to mobil 1 in the L or anything else.

Hello Fellow Lightning Owners!
I changed the oil in my '01 this afternoon @ 1000 miles, and the oil was still highly viscose and clear. I looked at several stores, including Wal-Martinez ect and was not able to find a synthetic 5w20 oil. I went ahead and renewed with Motorcraft 5w20 for now. I've always used Mobil 1 5w30 and enjoyed great engine sevice and life, but until Mobil 1 comes out with the specific requirment I'll use the dino grade. Anyone heard when Mobil will produce the synthetic 5w20?

Hope that helps with some decisions. That came from Mobil 1's site.

Take care,

BfB

I'm not so sure that you can make this statement!

As far as technology is concerned, the automobile is the last to benefit for economical reasons, then motorcycles, then aviation.

Governments invest large sums of monies into piston aircraft in WWII and beyond, then motorcycle steal aviation technology because of matching piston speeds, this spawns cheaper technology that the automotive industry adopts for higher mileage and better engine life.

This piston technology has to do with super hard piston rings and cylinder walls, while one offs can be machined/engineered pretty easily, full production methods are another story.

Now that that's out of the way, I know that high performance motorcycle engines from Japan have to be broken in at the factory with a special abrasive oil, otherwise it would never break-in on the street with normal use. While this method wouldn't be a problem for most of the vehicles that BFB states it could be a production problem for a normal non-performance engine (Ford Focus). I don’t think that a Ford Focus uses the same ring material as a Vett, so the in-house break-in isn’t necessary, but I wouldn’t use superslick synthetic oil in my Focus either if I was trying to get the last 5% of performance out of it before break-in.

So just because a high performance Ferrari engine uses synthetic oil from the factory doesn't mean that an unbroken in Focus engine can use it also.

Some assumptions have been made in this statement and the author refuses any liability, but if for some unforeseen reason the author is correct then the said individual accepts all win falls and said copyrights, taxes and liabilities willing.

 

What is this 5W20 crap. There ain't no requirement for 5W20, its 5W30 that ford recommends.
