Really impressive... and a lot of life left with a TBN of 6.35.

Is there a mistake for the viscosity? 6.1?

What is your driving habits? Lots of highway drives?

 

[Pablo]

Looks excellent. Something is goofy with the viscosity.

 

[GROUCHO MARX]

Amsoil in left column or right?

 

[Cup of Joe]

Amsoil is the left

I do almost exclusive highway/rural driving when ever possible. The vis and the ads are what stood out to me. I haven't had a chance to call the lab, I wanted to post it as I received it until I get a chance to call. Oil is still in the car with just a top up.

This engine has always sheared its oil even XLM sheared. The PP sheared the least of any oil I have used in this car but it had 4k less miles.

A question to the experts, if you allow me TaterandNoodles:

With Oxidation at 36 and Nitration at 27 (abs/cm ?), how far can he go?
What is the limit for these two data if you don't want to take too much risk for your engine?

Thanks.

 

[TeeDub]

Pesca,

The generally accepted limits for Ox/Nit are 50 abs/cm ...I'd also use a lower limit of 4.0 on the TBN. Best guess? This batch of oil could be run out another 4000-6000 miles.

The traces of K & Na are from salt laden air (VA Beach location)

It depends totally on the exact oil tested virginally. Without that then nitration and oxidation are not a lot of value.

Congrats, you challenge Bruceblend 0w-20-LITE for low end 20 grade visc.

(visions of the Rover Discovery commercial where the upscale couple pick up the stray dog in the rain while in traffic)

Courage

 

[buster]

I wonder why there is such a difference in the ZDP between both oils?

 

[Steve S]

Most impressive. The zinc if accurate doesn't seem to matter???

 

[Cup of Joe]

I called and they say the viscosity is correct. I didn't think this engine design was all that hard on oil. Its a 1.6L CVVT with a short chain between the 2 cams but the timing is belt driven and not a chain. I would have thought any of the nissan, toyota or honda's to be allot harder on their oil since they are full chain.

What are the odds if I do a couple more miles I will be in the 10wt range? This oil is still in the car, when has it sheared to far?

 

[zoomzoomlx]

My mom has an 06 Rio with this motor. Should I switch the oil over to something better than the Supertech dino 5w-30?

You should be fine as long as you don't run it to long. This engine has been chewing up TBN and Viscosity in every oil I have run. Your 5w-30 is easily a 20 before you change it. I've posted some conventional changes over the last 2 years. Pennzoil, havoline and gtx although the gtx was the shortest.

 

[zoomzoomlx]

Do you think 4k miles would be pushing it for an oci interval?

 

[Cup of Joe]

4K should be safe. At 5k miles the TBN were all fairly well shot. Don't forget how the car is driven will matter as well. It only takes me 2 months to do 4k miles.

 

[TeeDub]

The long term implications of these two analyses should be clear for all to see - it won't be long before the Koreans are really pushing the Japanese on the overall quality front.

My question for Detroit is why can't you mass market a refined, four cylinder engine that wears like this??? At first glance this looks like a 200k-250k motor to me.

 

[zoomzoomlx]

Did the GTX fare the worse of that with the Havoline and Pennzoil?

 

[Cup of Joe]

No it just had the shortest run only 2k miles at the time with low mileage on the car. I would call them all equal.

Ecotec appears it's on a similar level as the Japanese 4 cyl engines.
