both should be about the same. GC is a thicker oil so their 30W is closer to a 40W while mobil 1 is a thinner oil so it's 40W should be closer to a 30W. each should yield similar results. FWIW, per patman's suggestion, the only mobil 1 oil i'd run is their 0W-40.

let's get something straight: mobil 1 is good oil. mobil 1 5W-30 is good oil. it's just not good for an LS1. mobil 1's 5W-30 isn't a true 30 weight, it's closer to a 20 weight. it's too thin for an LS1. that is why our LS1's tick, consume oil and sound like a sewing machine. most people use mobil 1 and it's too damn thin for the LSx line!
switch to german castrol 0W-30. it's a thicker oil and better suited for the LSx line. you'll be amazed how much quieter your engine is. it's more like a 40 weight mobil 1 oil. the only mobil 1 i'd put in my car is 0W-40 or 5W-40. i'd never use their 30 weights, they're like water.
if you have tick or that sewing machine sound, try GC 0W-30. my engine is amazingly more quiet than when i bought the car and it came with XXX oil in it. the only noise out of my engine bay is the belt noise. 2,500 miles later and it's still pretty clean too. i'm a believer.
ask patman, he'll tell you. he runs german castrol 0W-30 for 9,000 miles in his corvette and his analyses come back saying the oil could go longer. it just may be the best oil out there, especially for the LSx.

In Canada you can get it at Walmart and Canadian Tire though.

yea i can look for the GC 0W30.. that is what you recommend for the ls1???

if you can't find GC 0W-30, get mobil 1 0W-40 or 5W-40. i would probably buy 0W-40 since it would give you better startup temperature, run better in the winter and still thicken up the same when it gets hot. just my opinion on that one, i have no real data pointing 0W-40 is better than 5W-40. i'd have to ask patman to chime in on that one

LOL i like how you are m aking sure to say the right thing. you got torn in my last thread

GC 0-30 all the way, i ran 10-30 m1 15K mile formula, and now GC 0-30. No contest, I like the GC. Motor is queter and oil pressure a little higher. GC also uses no viscosity improvers because the base oil is really good.(Patman can clarify)
