I have used Mobil 1 10-30W in my 93 EB since it was practically new. Changed over to Mobil 1 at 8K as I tow small travel trailers usually 5-8 hours one way in the summer from Central Texas to the Texas coast. I figured I needed all the heat protection I could get as outside tempertures range from 100-112 degrees. I understand, too, new Corvettes come with Mobil 1 as their "factory fill". Mike

my 2 cents

my 2 cents,
The reason why switching to synthetics on a high mileage vehicle could cause leakage is that with it's aggressive detergents. It could dislodge scum left behind from that of regular oil that over age keeps the oil in.
Synthetics aren’t really thinner per say, a regular 5W/30 is the same as a Synthetic 5W/30. (25 cents is 25 cents whether a quarter or 25 pennies) Synthetics don't thicken as much at EXTREME colder temperatures and can handle higher temps.

BTW, if you look at the tech pubs on all the pubs, they are all pretty much that same, although some of the 0W30's and 5W30's have a higher breakdown temp.

FWIW, I use Mobil 1 0W30 all year

Puralator is a good one, that's what I use, well, that's what was recomended by my moms husband and he's a mechanic and his trucks all have over 200 miles and still going strong so I'll trust him.

Heres a tip for you. The Purolator1 and the Motorcraft are the exact same filter. $3 vs $5.

Yeeeah...

My X didnt leak when i bought it from a private seller, then after i got the oil changed and switched it to synthetic oild at 70k miles, it started to leak....maybe thats why it leaks

That answers a question i guess...

I don't think a puraltor and Motorcraft are the same. A motorcraft has a special trap filter inside. You need to ask for the details about it because it is really way too much for me to explain but I have lots of friends at Ford and they hate fords but they still say go with the Motorcraft.

Regarding the Motorcraft filter...

This is an interesting filter. Basically, it is a Purolator Pure One filter cartridge in a Purolator Premium Plus case. Don't be fooled by the differently shaped holes cut into the oil inlet. This is the only difference. This is a good filter design and if you want to get a Purolator Pure One filter, get this one instead: it is cheaper
