So what happened at the end of 1990 ?

Here you go...castrol don't do a true synthetic...it's a Group III
Sorry guys, a bit of cut'n'paste here.....
The Castrol does give big bangs for your bucks...but it's not a full synthetic.
I had exactly the same thing with Morris's 15-50 'fully synth' last year.
It's not a group IV...therefore not a fully synth by definition.

Almost every lubricant used today started off as just a base oil. The American Petroleum Institute (API) has categorized base oils into five categories (API 1509, Appendix E).

The first three groups are refined from petroleum crude oil.

Group IV base oils are full synthetic (polyalphaolefin) oils.

Group V is for all other base oils not included in Groups I through IV. Before all the additives are added to the mixture, lubricating oils begin as one or more of these five API groups.
Group I
Group I base oils are classified as less than 90 percent saturates, greater than 0.03 percent sulfur and with a viscosity-index range of 80 to 120. The temperature range for these oils is from 32 to 150 degrees F. Group I base oils are solvent-refined, which is a simpler refining process. This is why they are the cheapest base oils on the market.
Group II
Group II base oils are defined as being more than 90 percent saturates, less than 0.03 percent sulfur and with a viscosity index of 80 to 120. They are often manufactured by hydrocracking, which is a more complex process than what is used for Group I base oils. Since all the hydrocarbon molecules of these oils are saturated, Group II base oils have better antioxidation properties. They also have a clearer color and cost more in comparison to Group I base oils. Still, Group II base oils are becoming very common on the market today and are priced very close to Group I oils.
Group III
Group III base oils are greater than 90 percent saturates, less than 0.03 percent sulfur and have a viscosity index above 120. These oils are refined even more than Group II base oils and generally are severely hydrocracked (higher pressure and heat). This longer process is designed to achieve a purer base oil. Although made from crude oil, Group III base oils are sometimes described as synthesized hydrocarbons. Like Group II base oils, these oils are also becoming more prevalent.
Group IV
Group IV base oils are polyalphaolefins (PAOs). These synthetic base oils are made through a process called synthesizing. They have a much broader temperature range and are great for use in extreme cold conditions and high heat applications.
Group V
Group V base oils are classified as all other base oils, including silicone, phosphate ester, polyalkylene glycol (PAG), polyolester, biolubes, etc. These base oils are at times mixed with other base stocks to enhance the oil’s properties. Esters are common Group V base oils used in different lubricant formulations to improve the properties of the existing base oil. Ester oils can take more abuse at higher temperatures and will provide superior detergency compared to a PAO synthetic base oil, which in turn increases the hours of use.

Thats all makes sense but what makes you think Castrol Power 1 Racing is a group III oil ?

I'd be surprised if Castrol would print "Fully Synthetic" all over it if it wasn't true.

castrol is today a NOquality oil > mean NOgo in hi performance engine
easy , you still think castrol is new, fresh oil ?
is not the only company using that way
they can re-refine oil by taking out the contaminants and adding the additives but still shitty overpriced Noquality oil

Right that's it!

It's this or nothing!

no sorry , 300v is a good oil for racetrack use , but for normal street use is def better change it after 90-120 days

Tiz for my Track Bike Derchef.

All the lads over on TDR reckon it's the Daddy if you Race or Track Day your bike, downside it's £50-60 for 4 Litres.
