SOPUS Caterham blend?

[ledslinger]

I used up some orphan oil while thinning the 3.75 liters of 5W40 Shell Helix Ultra with 1 quart of 5W20 Pennz Ultra and 1/2 quart 0W20 Pennz Platinum. May not reach toward the goal of creating a high VI 0W30 like the Exxon Mobil original Caterham blend, just getting closer to the specced 5W30 of my 2.7 Liter 2000 Chrysler Concorde with 92K miles.

I run 0W40 Mobil 1 and 5W40 Pentosin or 5W40 Lubro Moly with no apparent negative consequences instead of the specced 5W30. I've had hot idle light flicker with 5W30 Pennz Ultra and 10W30 Schaeffer 7000 blend. Never with the 0W or 5W 40's.

That was 3.25 Liters of 5W40 Shell Helix Ultra.

No offence, but it's a blend, not a CATERHAM blend.

CATERHAM chose to specific oils for his blend to achieve an outcome, not really trying to acceptably use up leftovers.

 

[ledslinger]

As noted. Its close to that blend with SOPUS products.

 

[Shannow]

So my 40% Delo Gold Ultra 60% Caltex C3 synthetic is one too eh ?

 

[MobilinHyundia]

NO!

This is your own blend. Name it ledslinger blend or hunter's soup blend or whatever, but to call it Caterham blend is dishonest.

That's not the OP intent. He is just blending oils.

This is a good point. Why haven't the peope who know about these things started explaining why this should or shouldn't work well in this engine?

With nearly 3000 posts you should have learned something about oil by now....eh.

I have been reading and learning, yes, but having nearly 3000 posts doesn't mean I know anywhere near as much as the people I've been learning from. Also, if all of my posts were useful there wouldn't be so many of them.

 

[ledslinger]

If all my posts were useful I'd be even less interesting.

I learn something new everyday.

Using the Widman viscosity calculator, and entering the Pennz Platinum and Ultra as 1.5 quarts of 5W20 Ultra, the mix has a 40 degree cSt of 64.5, and a 100 degree cSt of 11.36. It appears I did indeed make a 30W.

.........A very thick 30-weight.

 

[ledslinger]

Not as thick as German Castrol 0W30 12.1 cSt at 100 degrees.

If you're getting a low oil pressure warning light with a 30 wt, why are you trying to make another 30 wt?? Why not simply use a 40 wt that maintains oil pressure??

With that kind of blend, you probably have a 5w30 slightly on the thick side of average. The half-quart of 0w20 will not take the low temperature viscosity down to a 0W.

This fill will be in during a northern Missouri winter where below 0 F usually happens. Trying to nail the viscosity that won't cause hot idle low pressure without being excessively thick.

Another oil beside the 0W AND 5W 40s that never caused hot idle light flicker was GC. Castrol Edge is a thin 30W so I supposed it shouldn't be surprising it might be marginal in my application with some shearing. The 10W30 Schaeffer 7000 surprised me that it would cause a hot idle light flicker.

It is also an experiment and a way to use up the orphan quart and a half of xW20 Pennz. I've got lots of 0W20 Toyota and Subaru for my wife's Accord.
