Castrol Edge EP vs Mobil 1 EP

[david6245]

Hello, I am new to this forum. I have been using Mobil 1 EP (5w30) with Mobil 1 EP filter, in my 2003 Toyota 4Runner. 211,000 miles, 7,500 OCI. It has a 4.7L V8 engine. I drive 50 miles round trip per day, majority is highway driving but in slow traffic in the Southeast USA.

I am considering switching to Castrol Edge EP (but still using the Mobil 1 filter) since it is currently $3 cheaper per 5 quart bottle. What are the differences between the two if any?

Thanks,

David

I recently switched my Camry from Mobil1 to Castrol EP and the difference on start up is noticeable, but isn't major. You really can go wrong with either. M1 has the promo going right now.

Neither oil he mentioned is on that list.. I don't think PQIA tests EP oils..

Understood, but doesn't it at least give insight into the difference in additive packs? Mg vs Ca etc. I guess search for VOAs on the two then...

Why switch if it's working.

Apples and Apples. May need something more drastic.
Like a MB spec LL. I was more impressed over with the Magnetec than the edge - but for normal intervals.

Crank speed or noise?
Personally, I find them both rackety.

Magnetec & QSGB seem to be the quietest, Fwiw.
