Switch to a different oil type recently (Mobil1 5w-30 to Castrol 5w30) and noticed the charger just doesn't sound like it should once the engine gets hot and the oil thins out. The oil is new but it seems like its breaking down too much. This lead me to the conclusion that maybe some oils work better for supercharged engines and if so what type would that be? Or maybe im just overthinking things cause i would not think oil would have a huge impact.

(I do not winter drive it, however it is stored in a garage at sub-zero temperatures)

Why? Storing it can do more harm than driving it.

Just drive it. Infiniti can take a winter drive.

If you saw my car and the conditions of were i live you would understand.

Do you have a pressure gauge installed? That will tell you basically everything you need to know about how the engine likes the oil. If you're on a stock motor I'd say probably a 10w-30 maybe 10w-40 when it's hot out.

Built motor it depends on what tolerances we're used.

Ohh and for pure track purposes you'll switch to something like 20w-50

I have fully built internals, only have air/fuel and boost gauges installed. I think i try a few more different types until i find the sweet spot.

That's the best way honestly, try out a brand, run for 3k and do a Blackstone engine oil analysis on it. See what kinds the motor runs the best on.

I take it you have never tried driving a boosted G35 in slippery conditions before???

Get a custom map just for winter Sort of like valet mode lol.

Most sane drivers would avoid driving even a completely stock vehicle in slippery conditions.

Let me see if I understand your post.
You've spent thousands of dollars in mods to your vehicle that you cannot use for a substantial part of the year due to slippery conditions and you are worried about what oil to put in it while it just sits and depreciates in value?
You pay for insurance while the vehicle just sits with non use and you purchase another vehicle along with additional insurance while the other vehicle sits out the winter?

You are a financial genius.

AMSOIL synthetic 5W/30 and you really need an oil pressure gauge so you know what's going on internally. I picked up another 4 psi using AMSOIL at 2400 RPM!

So now people are insane for taking their stock trucks or cars in slippery conditions??? Even though that is the best way of learning how to drive in those conditions. Now, attempting to drive a G35 in the same conditions that has been modified to go much faster than stock is just plain stupid.

Many socialists lack the ability to comprehend my posts so lets give this a try. Over 95% of vehicles depreciate in value so that point is irrelevant. Many of those who do heavily modify automobiles are not trying to flip their property for a profit.

From a geographical standpoint, the majority of the country does not see wintery conditions for a "substantial part of the year", so also irrelevant unless the OP lives in Alaska. It is extremely rare in the US for an area to remain at subfreezing temperatures for over 6 months.

Believe it or not, those who have motorcycles, show cars, race cars, expensive cars, nice cars.....etc spend their money because they enjoy it. So yes, some people may pay for insurance for a couple of months of non-operation depending on where they live.

Honestly it all comes down to tires and driver skill. WHP is irrelevant until you start pushing greater than 250whp per 1000lbs of vehicle weight, yes performance clutches make it a little more difficult to launch the vehicle but I've driven a 700whp full posi with 1500rpm stall converter rwd in the snow/ice just fine (yes it actually did suck to drive that one), 850whp manual transmission newer rwd in the snow/ice just fine, a 1965 800whp 396 4spd chevelle in the snow/ice just fine, a harley davidson in the snow/ice just fine, a GSXR in the snow/ice just fine... you have to know following/braking distances, how and when the vehicle will slide if it locks up.

Winter/snow/ice tires makes the job at least 5x easier, driver skill is EVERYTHING.

My brother rides HIS Harley 365 days a year and doesn't even own a car, we live in the land of freezing rain, he's never had an issue.

A man's political leanings doesn't factor into how well you can drive in the snow.

Correct, but when someone has the mentality to try and throw insults, than I will give them zero respect.

Suspension also plays a part with a car's ability to perform on slippery surfaces. I'm only at 500wtq, and with little throttle I've broke traction unintentionally at 60mph+ on the highway in just rain. Without some type of studded tire or chains which would not fit, my car would practically be useless on ice. Snow and slush are one thing, ice on the other hand..

I don't need your respect!

So you were insulted when I raised the fact that you've spent (wasted) thousands of dollars perhaps without proper insurance and now you admit that not only is your vehicle unsafe in rain as well as snow, I would have to guess that your vehicle is most likely unsafe to be driven on any public road even in dry sunny weather.

You sir are a hazard to the public by putting such a vehicle on public roads. I hope you carry at least a one million dollar liability insurance policy because if you are ever involved in an accident even if not your fault even a country bumpkin lawyer can take you and perhaps your parents for every penny of assets that your entire family has.

Take your vehicle to the track and ask others there about what oil they use
