Just a heads up. Costco will have Mobil 1 oil on sale for $8 off per case. The sale runs April 4th to 20th. You will need a coupon, which they give away at the store. Limit is 2 cases per coupon. They should have 10/30 and 5/30 available.

 

eh my rotary breaks down enough on royal purple

 

what do you mean break down on royal purple??? my 3rd gen runs fine on royal purple, did u have problems please telll THANKS

 

no I'm saying royal purple is the one of the best and rotarys are bad enough already without using the mediocre mobile 1 brand.. by the way which oil do you use? 20w50?

 

I always buy the Chevron brand @ Costco for over 10 years with no problem.

 

i always buy at costco the chevron brand for over 20 years with problems.............the lines!

 

I always buy the Costco brand @ Chevron for over 30 years with no problem.

 

Mobil 1 is one of the better ones. Car problems are usually unrelated to oil. But I'm still sticking with Royal Purple for complicated reasons not major enough to be worth mentioning.

 

Reaons: Purple is pimp n fresh yo!

 

^ Exactly.
