Mobil Super vs Chevron Supreme

[Stewart Fan]

In a 10w-30 flavor for my '07 Yamaha F150.

I've been using Chevron Supreme since I bought it new,but I'm out of oil.

I can get Mobil Super at O'Reillys's for $1.99 a qt,or the Chevron at Costco for about the same.

With Costco's $9.00 off coupon, it makes Chevron $1.67/qt. I would back up the truck at that price for a great 5-8K OCI oil.

If the CS is that cheap,I'll stick with it. I couldn't remember exactly what Costco sold it for. I had the coupon figured into the price.

I miss the days where Schucks or GI Joes had the CS on sale for $.59 a qt every few months. I had something like 10-12 cases for a while.

I heard synthetic is better than Dino and causes your engine to last longer even if you change your Dino regularly, is this true?

No its not true, your engine will last approximately 4-7 times longer if you use dino oil and change it twice as often, its been proven by many SAE papers!

troll aside, I'd take the Chevron Supreme over just about any other dino oils. It's a Group II+ base stock with one of the best add-packs of any of the mass market oils.Just keep the intervals at a reasonable length and you're good to go a LONG time.

150 hp outboard cost $$$$$.$$... you are looking to save 2.00$ on an oil change??

I would use a HDEO but that is just me and I havent owned a boat since 2004.
