I dont kow how many times this has been brought up and frankly, i dont care. I was wondering which brand of oil are you guys runnin on your B-series. Synthetec, non, 5W, 10W; mobil, pennzoil...which brands are you guys runnin....im runnin Mobil for now...what about you?

 

wal mart 10w30

 

castrol syntec 10w30

 

castrol 5w-30 (non synthetic) for winter.... 10w-30 for summer/hot months (non synthetic)

 

mobil 1 10w-30w

 

I always run Mobil 1 Synthetic and I would never stop using it. I've blown a few motors due to dirty oil, and Mobil 1 seems not to get dirty as fast (personal opinion).

 

B&G synthetic - oil change every 10K or so.

 

Depending on the car mobil synthetic 5w-30 or 10w-30.

 

mobil 1 synthetic (it's the best!)

 

Royal Purple 5w30, but use Mobil1 5w30 when I don't have the $$ for Royal Purple. Both great oils, but Royal Purple makes the car feel so much smoother than Mobil1.

 

Castrol Syntec (%100 synthetic) 5w-30.

I've seen comparison charts showing all the leading synthetic motor oils. Amsoil is the best, and I've used it before. Pretty much any %100 synthetic motor oil will provide excellent protection, but the Castrol Syntec seemed to be the best bang for your buck according to Amsoil's charts.

 

mobil 1 5w-30 .... full synthetic is the only way 2 go power

 

Valvoline Duralend. That way you still get syth. but dont pay for it entirely. Call me cheap, i dont care. 10-30 all year.

Blaze

 

Motul 8100

 

Mobal 1 if i'm feeling cheep, Amsoil if i'm not, both 10w-30

 

Castrol GTX 5W-30 or 10W-30.

I don't believe in using synthetic oil, as long as you're changing it every 3000 miles. I change my oil regularly every 2500-3500 miles, and it comes out rather clean - so I feel that synthetic would just be pissing money away with such a short change interval. Especially with Mobil 1, since it is thinner than most other oils and thus tends to disappear more quickly in between change intervals than other oils; not to mention it is far more expensive than conventional oil, as most systhetics are.

It is generally accepted that the best engine oil from a protection standpoint is AMSOIL, but again I personally don't feel it is worth the money as long as you change your oil frequently.

Valvoline 5w30...changed every 3-4 hours.

Every 3-4 min here.

 

redline 5w-30

 

Most likely the castrol 100% synthetic you think you're using isn't really a synthetic.

I'm currently running 15-40 castrol non-synth and will switch back to 20-50 when it gets warm again. I'd run mobil drive clean if I could find it in heavier weights.

I am a Mobil 1 guy. It cannot be denied that it is one of the best. A few others I'd use but Mobil 1 is expensive enough.

 

I use good ol' dyno juice. 10W - 30
