Torco SR-1 Synthetic 5W-30

[Motorbike]

This oil was used primarily hi-way commutes from 11-28-03 - 1-06-04 for a 998 mile total in my 1.6 Mazda Miata and was pulled early because of severe motor noise on cold fire below 20f . The second cold fire at sub 15f did it for me since I wanted to drive the car a bit more this winter than previous and it's a pain getting it out of the shop so it stays under the carport in the concrete freezer

This is a HP oil that did well above 35f for me and was run over 7k rpm daily during this interval. I currently am using the Torco SR-1 5w-20 in the car and will use the 5w-30 again when winter is over .I think this oil will protect better than this shows . My car never liked sub 35f starts anyway with any oil .

The first column is the Torco second is Mobil SS 10-30 at 3200 miles and 5 months with 3 ounces Lucas UCL in every tank

Motorbike,

Thankyou, thankyou, thankyou for your results. I am currently running the SR1 5W-30 and was wondering what the specs for this oil look like.
A rather comforting high dosage of Moly will allow me to sleep better at night

. I recently change from Redline 5w-30 which I used exclusively since the engine was rebuilt. I'm going to send in this batch for UOA after about 4500 miles. Keep us in the loop as to how the 5W-20 performs.


regards,

Scotto

You GOT moly!
Do you know the amount in you virgin batch?
What about MPG, did it change?

I'm surprized others haven't commented on few things.

a) This oil only had 998 miles. (Wear) Numbers are sorta meaningless, but lead at 8, when M1 with 3200 miles had 1 ppm?

b) Why would a 5W-30 full synthetic (ester?) oil cause start up noise at 20° F or even 15°F? I run 15W-40 synthetic in the winter....10°F and no noise, I'm not bragging, complaining or advertising, but something just sounds odd.

c) Yeah you got Mo, but what did it do for you? Not sure a street oil really needs above 200ppm.

Yes it concerned me for a moment too.
Granted I am no exper at reading these things on the oil.. I fly by the seat of my pants.. But:

1.I consider the Tin and lead a more of an issue if it was longer or had a trend of more info and it jumped, but all the other metals look like they came down or remained the same to me...

2.Have you ever gone from a long OCI to a short one? Although theres not a lot of info here to decide the info given to me looks just like an oil can do when you go from long to VERY short.
I'm not saying it will always do this, but I have seen short one with the same OIL produce much higher numbers in a few wear metals...

Now that severe noise, what was it, lack of oil

maybe the berings taking a beating???

All I know is the other metals dropped... so maybe the trace of moisture in there had its damaging effect on a cold morning (ICE

) I donno, I have no experience, I just can give it my guess based on my maybe flawed logic.
Any way I am late calling into work by 22 minutes gotta go

Just to mention, I've been running the Torco 5W-30 for a month as of today. When it hit 10F about a week and a half ago I had no problems firing the beast up; she ran just fine at that temp.

Bump

Look Mom , lotsa moly but no PE Ester and no copper elevation .

Things that go bump in the nite

 

[haley10]

I don't get the point.

 

[buster]

Redline with it's POE and Moly shows elevated Copper and Pb. Many theories/reasons why if you do a search. I've beat up on RL enough already.

 

[haley10]

I'm slow, but now I get it.

Thanks.
