Free case of Valvoline VR1 racing oil.

[Thugboat]

I know this has come up before, but, my Houston Cobra Club brothern are having a very detailed discussion about zinc content in oil at this time.

What has come up in this discussion is FREE OIL!! Check out the Valvoline free case of VR1 racing oil at the below link!!!!

Thanks - Printed and purchasing..... Always can use good oil...

I went on line to check on this oil, alot of negative feelings on the Corvette forum. I think there may be a reason they're giving it away.

I'll use it iin my BMW to make Sam happy.

Basically oil is oil. I know I will take heat on this one! Viscosity is much lower in newer cars. 30 wt in an old 70 model, 5W30 in newer....much closer tolerance. I use the Ford Racing Syn Oil QGT in my GT but really wonder why. Is it so much better than say Mobil1 or Castrol Synthetic?? I do use the Mann filters. They are the EXACT same/////irregardless of what Silverbullitt says lol. I go 5K miles between changes and think that is too soon. I go by miles, not mos or years.

Thanks Larry! Looks like a good deal!

Is there really anything "Humble" in Texass?? ( Couldn't resist )

I use the Mann filters as well.

If EP went by miles he would never, ever, change the oil! :lol

OK....but how do you choose amongst their options?:confused

10W30 weight
20W50 weight
30 weight
40 weight
50 weight
60 weight

I have never heard of oil grades described simply as 30, 40, 50 weight.:eek http://www.jegs.com/p/Valvoline-Racing/Valvoline-VR1-Racing-Oil/761749/10002/-1

Since I am sticking with Motorcraft 5W50 for the GT, I asking this question with respect to 'regular' passenger cars. How do you choose?

(BTW - I have gone to the Valvoline website and have read their material which doesn't give any detail for making a decision...that I can understand - http://www.valvoline.com/pdf/VR-1_Synthetic_Racing_Motor_Oil.pdf)

Go with the vehicle manuf suggested grade. Usually on the fill cap or in the owner's manual.
20, 30, 40 etc are "straight weight" oils. Been around a looooong time....like EP.

EP was around when the oil reserves were non-existent.

 

[Art138]

For a climate such as here in Florida, 40 has been recommended for the summer.....I can't seem to find the oil here at pep-boys or advance....I guess I will try jegs....I will stick to 5W-50 for the GT......

Thank you....though I don't understand what 'straight weight' means.

The following from one of the oil gurus on the National Corvette Restorer Society forum:

"Some of you need to go back and look at the Web references in my oil article from the Summer 2008 Corvette Restorer, specifically the engine and gear oil viscosity range comparison chart at 100C:

http://lubricants.s5.com/viscosity_c.htm

1. The total range of SAE 30 through 50 absolute viscosities is only about 2:1

2. Engine oils use SAE viscosity grades from 10-60, and gear oils use 70-250 in order to distinguish them from each other. However, an SAE 75W gear oil has about the same absolute viscosity as the SAE 10W-20 engine oil range, and a SAE 90 gear oil overlaps the SAE 40 through 60 engine oil ranges.

So a statement like "why not use SAE 90..." indicates an fundamental lack of understanding of the SAE viscosity grades used for engine and gear oils, and a fundamental lack of understanding of the differences in blending oils for engine and gearbox use, including the all-important additive package.

I have never observed much if any difference in hot or cold oil pressure between 10W-30, 15W-40, and 20W-50 in moderate to high ambient temperature, either cold start or fully warmed up. Some report differences, but they are a minority.

One of the reasons to use a higher viscosity range is engine oil operating temperatures. In hot weather low speed driving, or spirited driving in hot weather, and especially race track hot-lapping, engine oil temperatures can well exceed 100C, and a higher SAE viscosity grade will provide insurance that absolute viscosity will remain high enough to support the bearing load and prevent metal to metal contact. The higher the absolute viscosity, the higher the oil film strength in the bearing, and the more load it will support."

And, this too is good reading material. If read, you will know more about oil than most will. Hope this information will get the answer you are seeking. DJ.
