When is GC NOT a good oil for the application

[11secondoldmopar]

The title says it all. I love this stuff and have nothing but good things to say about it. I still have 70 bottles of green left, so the question is:

In what vehicles and applications would you absolutely not choose GC? I'm here in Mid Michigan, and I run it in everything but my flat tappet big horsepower 440's.

I use it in all my modern, late model cars and broken in small engines, is it still the best oil available in your opinion for these apps?

It doesn't seem to work as well in Honda engines as thinner oils do. It's just a tad too thick for them. I wasn't that impressed with how it performed in my wife's 2000 Civic so I switched her car over to the thinner Syntec 5w30 (which is 9.7 cst, compared to 12.2 for GC)

I wouldn't use it in a VW pump-duse TDI engine, where a VW 505.01 approved oil is recommended. I'd use it in just about any gasoline engine without hesitation, with the exception of high-horsepower racing engines.

Not good for Ford modular V8's. Once again, too thick for this engine and hurts performance. I wouldn't use it in any vehicle that specs 5W20.

Ok: Thick oil = hurt performance. Does that also = more wear on engine due to thicker oil?

 

[GT11]

I use it in my honda that specs 5W-20 and it works fine.

I would not use it in an apllication that needed high additive levels and/or higher viscosity oil.

I would not use it in a Detroit or Cat...

I would not use it in a Suzuki GSXR1000

I would not use it in a Carbed, Solid Tappet Big Block Chevy.

I would not use it in a H-D Twin.

Has anybody used it in a GM 6.0L Vortec V8 that is spec ed for 5w30?? I leave my GMC outside in the winter and was thinking of going with GC since my autozone has the green

Should work great, I'd use it without hesitation in any vehicle spec'd for a 5W-30.

Made my Honda sluggish. Use 5w-20's where applicable.

 

[cguy]

8.1L GM. I tried many types from Delo 15w40, M1 Truck & Sport to CS 5w30. I like the GC the best.

I have no idea what you're talking about...

I would not use it in my 05 and 03 Hondas that call for 5W20. They get 8K intervals with their own elixer of life.

 

[kcryan]

5w-20 vehicles, and i wouldnt put it in a E46 M3 (spec says use castrol 10-60)

 

[Curious Kid]

10w-60!?! Dang!!!

a coworker has a 04 M3. theres a big sticker under the hood that says to only use "Castrol Racing High Performance Synthetic 10w60 Oil" and it states that any other oil will void the warrenty. BMW can get away with this because they offer free oil changes throughout the warrenty period.

Perhaps but the M3 is very picky about oil. Wonder what the 10 cylinder 500 hp M5 requires?
