Mobil 1 is In all my rides including motorcycles. Results from racing has always been great.

 

Mobil 1.

In reguards to older engines leaking:
In older engines(before OBD II days), the seals can shrink from the reaction with PAO(polyalphaolefin) based synthetics. The additives package in synthetic engine oils must be formulated to control this reaction otherwise youll probably get leaks.

 

So, do you have contact an Amway rep and have them come to your house to buy the stuff.

I'm guessing you mean Amsoil. Thats a funny typo! Brought back memories of my childhood and having the Amway sales person show up at your door selling shampoo and stuff.

Right now I'm using Motorcraft cos I have the Extended Service Plan. Maybe after that is over I'll switch to Mobil-1 or Amsoil. I've had great success with Mobil-1 in the Porsche I used to own. Only drawback is the price.

 

I'll use whatever "dino" oil I can get in 10W-40. I'm not picky on the brand.

 

Here's an interesting take on oil changes from the truth about cars

Personally, right now the motorcraft 5W20 from the dealer is in there, but I will be upgrading to mobil1 in the spring

 

If using synthetic, Mobil 1 all the way. If using conventional, Castrol GTX all the way. Or, original factory oil if getting done at the dealership. those are my three choices

BUT, ABSOLUTELY NO NO QUACKER STATE AND NO PENNZOIL (which is now owned by Quacker state anyway). A shame, pennzoil used to be good

 

Mobil 1 here with Motorcraft filter. I try to change my oil at roughly 5500 miles. You can run synthetics for longer periods. 3K oil changes are a thing of the past.

 

i am getting 6 free oil changes from my Ford dealer right now so i am waiting for those to end then i will be switching to Mobil 1 or Amsoil but i still have 5 oil changes to go. saves me money till i have to flush the engine and make the change to full-synthetic

 

Castrol Syntec w/ PureOne filters.

 

+1

 

I've been been running RP with the Ford Racing filter! ........But I think I'm going to Motorcraft Sync Blend with the Ford Racing Filter !

 

amsoil 5w-20 with a wix filter every 5000

 

*one of the largest royal purple dealers in PA

I'm a little partial to them.

 

I use Motorcraft and NAPA gold filters. BTW: I thought full synthetic isn't supposed to be run in the Mustang because of variable timing?

 

Never heard anything about not running full synthetic in these cars. I doubt it would be a problem. I know the VVT is sensitive (supposedly) to different viscosity oil, (10-30, 10-40..etc).

 

Schaeffers series 7000 5w20

 

bbbbbbbbbbb

 

I use penzoil platinum, tests just as good as mobil 1 for less money.

 

Just used Mobil 1 for my first oil change at home. Previously, the dealer was using Ford Motorcraft for my first free oil change. The results of the poll here helped me decide what to use.
