Mobil1 5w30 and 10w30 grades (synthetic) are on sale at costco right now for 24.99 per case of 6, that's $10 off their regular price. I have a 5 case high wall I am building at home of the 5w30, recommend for you guys that use it to stock up.

 

How does this compare to Amsoil synthetic?

 

below I've listed data sheets to both amsoil's 0w30 signature series (their top of the line oil) and mobil1's supersyn oil, the one that is on sale at costco. For the money, the mobil1 is a great oil. They claim their TBN is 11, although TBN can trend downward sharply. The amsoil's tbn is 13.2

My recommendation would be around 7.5k miles or 6months with the mobil1.

im trying out eneos oil rite 0w50. so far so good.

 

For those without Costco Memberships. I just picked up a 5qt jug for $22 at Walmart. $0.23 more per quart, but still pretty good.

 

Already stocked up on a couple of boxes of this. I believe there is a limit on how many you can purchase, but Im guessing you could always exit and come back and buy more if you wanted to.

 

I have amsoil in the car now... Might pick up a few cases of the Mobile1... Ill be in contact with you Eugene for some service....

 

WalMart always has great prices on oil and other car items.

 

yeah got a filter and 5w30 of mobile1 for 30$ at walmart yesterday, didnt have time to pick up the eneos

 

Whats a good oil filter?? Where the HOT prices at?

 

That's a great deal; I will probably pick up a case for the Civic.

Royal Purple only for the G!

I also saw that Mobil 1 has a rebate for 10$ so that makes it 12$ for 5qts...

Wallmart's 5 qt jugs ftw. But that's a nice price at Costco.

 

Make sure you have your Costco coupon before going.... I had to find some dude in line that had coupons so I can get the $10 off.....
