Another interesting development in the oil scene I have been watching, but wanted to wait, until us oil nuts on the oil sites, get a better consensus going, before I report this oil here on NICO:
As we all know the Castrol Syntec line is a group III base oil and has not performed well in oil nalyses, even when compared to castrol GTX a great dino oil , with much lower price.
BUT in recent months castrol has qietly rebadged the famous EuropeanGerman Castrol SLX for US sale in a 0w-30 weight. its pour point (and pumpability) is <much> better at low temps than even MOBIL1 0w-30 despite being much thicker at 100C ( running temps).
This is likely achieved with at least a group IV more likely a group V base oil.
That would put it on a par with Redline ( group V) which is more expensive due to use of expensive base stock ( group V).
Since winter is coming and this is an excellent winter oil, I didnt want to wait much longer before I mentioned it here.
An absoutelty excellent choice for low mile engines due to its great start -up capability, but still good in hard running and its high hot running thickness for a 30 weight, means it will also do well in looser engines.
SOme may say: "Fred, wahts up you always say to stick with 40 weights like M1 0w-40, even in winter ,cuz they have good boundary layer protection and now you recommend a 0w-30?"
The solution to the riddle is, that the castrol Syntec 0w-30 is an unusually thick 30 weight,m about 25% higher hot running viscosity then MOBIL1 in a 0w-30 , actually it just barely misses being classified as a 40 weight.
At the same time it has the superior cold start characteristics of a group V so this is likely a group V oil.
Also it meets ACEA A3 some thing 0w-30's generally dont, even if from good synthetic stock.
Now Beware: very few places carry it ( usually AutoZone). many still carry the "old" 0-30 Syntec, Look at the bottle:If it says "meets ACEA A3" and "Made in Germany" its the real good stuff.Redline level oil for the price of Syntec!
If you buy the 0w-30 Syntec <be sure> its the stuff I mentioned above, as the regular Syntec ( basically same label except for the flags I mentioned) is not all that great and only meets ACEA A1 Something that can be achived or exeeced by a good blend such As Valvoline Durablend ( at much lower price)
While I will likely stick with my M1 0w-40 for now, I want to make members aware of this especially those that live in cold climates yet don't wish to sacrifice hard running protection for cold start protection.
Fred...
Also my current fill now is this oil.
