Yes, my Colorado is a diesel, but like I keep saying engine designs are closer together than forever, some run diesel, some run petrol.

40,000 mile service on the Colorado I left Magnatec DX 5W40 C3/Dexos 2 on the passengar seat, to replace the havoline 5W40...

the engine sounds more like a gasser than ever...


If it's the truth....it can handle the pressure !!!

You got a lot of miles on that car. Isn't only couple of years old?
What's C3? Is it diesel equivalent of A3/B4?

I bought 2 5qt of Casterol GTX Magnatec 10W30 Full Synthetic but haven't used it yet. Trying to get rid of some of my old dino first. I used to use Castrol GTX dino white bottles and still have a quart left. I may have to mix it with some Chevron Supreme to get rid of it. It maybe api sm or sl grin2

It will be 4 years old next month, I've had it for 3.5 now, and put 35,000 miles on it...so not a heaps fast rate.

Yeah, others have described it...the A's are high performance Gas, the B's are high performance diesel...the C is low SAPS gas and Diesel C3 is HTHS above 3.5...the Dexos 2 covers gas and diesel with a tighter spread on quite a few parameters...anything Dexos 2 IMO is a good thing for nearly anything.

I don't have the HTHS data, but assuming 3.7 cP for the Havoline and 3.8 cP for the Magnatec, Magnatec would have a thicker base oil by 0.35 cP, which is a lot and would explain the quietness. If I assume 3.7 cP for both, then it's only 0.15 cP higher.

Estimated base-oil viscosity (BO DV150) and VII content of selected oils

There's a side of me that always wants to say oil is oil.. how can one be louder than the other? But in practice, I know what you're saying Shannow. There are some lubes that seem to elicit more VT or TC noise, especially at start up in my V6. I have no way of like proving it in any scientific way other than my "calibrated ear" has come to learn how my car sounds. Or maybe I should say, should sound. Is it (louder sounding lubes) hurting anything in a meaningful way, dunno.. maybe or maybe not. That's an entirely different discussion.

Shannow. Are you pulling our leg? Experts here claim engine sound cannot be measured by the "ear" and doesn't mean anything.

I agree but I don't mention it here because of said criticism.

When a semi-boutique oil made the acceptable ticking of my VT vanish, I knew
When myself and 2 friends -hundreds of miles apart- noticed quieter engines with the same particular oil, I knew
And when a specced synthetic greatly quieted an engine previously lubed with cheaper conventional oils only, I knew

I'm tempted to try Red Line or Amsoil next.

Magnatec is all I run anymore. Smooth, quiet, and I think the low end torque is slightly better due to interaction with variable valve timing.
