So it's getting into the warmer months, and I'm thinking about switching to summer mode. What are you alll planning to use this summer viscosity-wise?

I am running Syntec 5w-50 in my blue car and Mobil 1 Truck & SUV 5w-30 in the black car (they were out of the 5w-40).

I run 0w40 year round. Next oil change I am sending a sample to blackstone labs.

Redline in either 5w40 or 10w40, but might try 5w30 since it is just used for drag racing.

I run Royal Purple 5w 30 all year. Once, in the winter they were out of RP and I used M1 5w 30 and my turbo bearings sounded off when oil temps were low, switched back to RP and the noise went away.

Royal Purple FTW!

What differences can oil make?

loustylez

all the difference in the world.

any reason i shouldn't go from Mobil 1 5w40 to Mobil 1 0w40 in a 30v 2.8? i hear a lot of people using it on 1.8T's and 2.7T's, but nobody on the 2.8 yet. only reason i ask is because i think 0w40 is a little easier to get around here than 5w40. but 5w40 is what's in there now from the last change @ the dealership.

IIRC the 5w40 is actually a M1 Delvac oil, which supposedly is MUCH better than the regular 0w40, but I could be wrong.

Best oil so far. 75 shipped for 12 qts isnt too bad either.

Has anyone experienced problems running 5w-30? I just put some cheap oil in it (I'm going to do a second seafoam flush in a week or so). and I bought some Quaker state synthetic (it was half off) in 5w-30 because it was the only grade they had. I'm new to turbo cars but I know you're supposed to run thicker oil (which apparently everyone here does). Should I return it to get some 0/5w-40? I can't find it on the shelf around here fore some reason. I currently am unmodded but plan to chip within the next few months.

any help is appreciated.

I run 10w-40.

Are there any real benefits/differences between them. I know the first number is weight [thickness?]. But what is the second number?

And what is th best oil to use for maximum performance.

ya im on 0w-40 syn aswell, and all ive noticed diff is that the oil temp gets higher faster

I went to wikipedia and looked up motor oil.

Also, it makes a big difference which engine you have. If i'm not mistaken turbocharged engines are supposed to run thicker oil.

the first number is what the oil is under 32 or cold, the second number is normal temp or the additive package. when oil breaks down its the additive package that breaks down so thats why ya change it, i run a10- 40 weight for the turbo thicker oil, longer engine life to a point. but ya cant get in ur car and beat on it right away gotta let it warm up vs o-40 its a lot lighter and will flow better but less protection. but u will get better mpg with a lighter oil

they're both viscosity ratings. they're variable viscosity motor oils. for example in your lawn mower you'll probably run a 30 weight oil. that oil has one viscosity grade and it stays the same. why? because its a frickin lawn mower and it doesn't need variable viscosity oil.

the wider range of conditions you'll be driving in, the more it helps to have a wide range viscosity oil. mobil 1's 0w-40 oil is great because when its cold (startup, winter/cold temps, etc.), its viscosity is very thin (0 weight) and it flows very freely. but when it heats up, it gets thicker and becomes a heavier weight oil (up to 40 weight). the higher the temperature, the heavier weight you want your oil to be so its not just constantly falling through the oil pan super fast and not providing adequate lubrication to the engine components.

make sense? now i'm by no means an oil expert [:D] but this is what i understand it to be. i could be wrong on some of them so anyone feel free to correct me.

personally i run mobil 1 0W-40 year round, but i'm sure there are lots of other great oils that i could be using. regardless, 100% synthetic is the only way to fly. ;) i'm also giving the lucas 100% synthetic oil stabilizer a shot this go round. lucas makes really good engine stuff so it should be pretty good.

Oil does NOT thicken up as you put heat to it...

I'm running Q torque power 10w30, but in about 1,000 I'm going to try Amsoil 10w40. I use a wix 51333 filter.
