Thanks Haley10, off topic, maybe not, I just bought my first diesel last cold January, that got me researching diesel oils, I have driven gas engines 25 years prior.
My finding with Esso is that CI-4/SL diesel/gas oils have better flow rates, better heat viscosity, and better TBN (30%more) than their Sl/gas oils.
I used to buy 5-30 Esso SL Superflo synthetic oil for $6.00 per litre, I now buy XD3 0-30 syn for 3.71 litre diesel/gas with better specs all around, even better than a 5-30.
Here is the clincher, conventional 5w30 XD3 CI-4/SL oil $2.50 litre versus SYNTHETIC Superflo SL/Gas oil $6.00 litre:
Superflo SYTHETIC 5-30/// XD3 DINO
TBN 8.6/// 12.2
PourPoint -39/// -36
100C viscosity 10.4/// 11
40C viscosity 58.2/// 65
This comparison is a DINO CI-4 5-30 versus a full synthetic 5-30 product. I paid $6.00 per litre for that Superflo for years, I could have paid $2.50 litre for Dino CI-4/SL and had same protection because I do 5K kms OCI. Now the XD3 syn CI-4/Sl 0-30 at $2.00 litre less blows $6.00 litre 5w30 synthetic superflo right out of the water.
My point being, it seems in Esso that any diesel/gas oil in syn or dino kicks --- on ony SL/gas Esso product syn or dino product. Possibly All oil companies CI-4/SL oil IS this much better than their respective SL products for winter oil flow properties, heat viscostiy and TBN protection???
Those who use their favorite oil may want to check out their oil companies's CI-4/SL rated oils for this winter cold driving conditions, may find better oil with better flow, heat viscosity and more Additives than the traditional SL/gas oil, the Sl oil probably costs more with less flow.
I cant feel anything but ripped off in buying SL/gas oils at 30% to 50% more than diesel/gas oils which have more protection and value for winter starts and summer viscosity protection.
How do other brands in CI-4/Sl do against their SL/gas oil for winter start performance, heat viscosity and TBN. If this should be a new topic then someone can go ahead and start one, sorry if I am too far off topic here, I believe most oil companies CI-4/SL oil is probably a better cold starter than their respective Sl/gas oils, anyone done their homework on other oil companies diesel vs gas oils for winter start properties?
