'03 Mazda Protege Oil

[Ty07allstar]

I have and 03 Protege that I autocross and daily drive with 93k miles on it. I am wondering what oil would be best for it. Right now it has Mobil 1 5w-30 synthetic in it but I am thinking about switching to Pennzoil Ultra Full Synthetic 10w-30 when it starts to warm up. What would you guys recommend?

either will work fine. I have about 180k on my Protege5 with a steady diet of M1 (and a stint with Amsoil) and it shows no signs of wear or deposits.

Take your pick. Still come out a winner.

M1 EP is a great product and worth the extra money.

I have an '03 Protege 5 - have tried the following:

Mobil Clean 5000 10/30 - quiet running
Pennzoil Platinum 5/30 - quiet running
Pennzoil Yellow Bottle 10/30 - quiet running
Valvoline Synpower 5/30 - tons of valvetrain noise

Personally, I'd pick a Pennzoil product in 5 or 10/30 and keep it there.
