Yes!5w30 Mobil is a c*nt hair thicker & shows good used analysis.Dino shears to 20 weight anyway
Flame suit on. This oil, 0w-20 will flow better at the range of temps that 98% of wear occurs, cold start and warm-up fully to +100c but protect as well as a higher viscosity oil. I just got done hammering out a post on viscosity on B5 Forum. A HT/HS viscosity below 3 works for 1.8t, the 3.5 of an A3 oil like Mobil 1 0w-40 is overkill unles you are over 275hp. I don't know exactly the HT/HS of M1 0w-20 but it is about 2.6, 2.9 is normal Mobil 1 5w-30 when it starts but it will shear more than the 0w-20, I SWEAR! The 0w-20 has a thinner designation and is thinner at most temps but very similar HT/HS because it's basestock is superior. Remember, the goal of oil design and selection is the thinnest possible oil that does not thicken too much when the engine is turned off so it can flow well on restart....when wear is highest. Oil is extremely thick at room and cold outside temps. It will not burn off or leak, all finished oils pass a seal compatibility test. Mobil uses Alkalated Napthalene to control the seal shrinking properties of their SuperSyn PAO. If someone cares to read up, I'll post some links on current discussion of white papers on the subject, but one Dr. who is an researcher for Ferrari, and does chat with Ferrari Techs as an expert uses 0w-20 in his new Maranello with no objections from the factory. The cold and normal temp flow of the thin oil during start and warm up outweights it's Extreme Pressure film protection against wear and there are additives that take care of EP situations where the film has broken down. Not my first choice, but it will work just like a 30wt but more hp, mpg, run cooler less wear and longer-lasting. FTR-thick and thin oils are identical visc over +250f so nothing gained except it will probally run cooler to begin with if thin oil is used. End of transmission.
