Yes, but they are both "synthetic and not synthetic" :-)
It is polar attraction.
What I do not like about Magnatec is 1) its ash figures 2) its ability to completely piss off hydraulic lifters that are otherwise silent 3) its tendency to gloop out of the pan which I found disturbing.
The problem at startup is how quick you can get pressure to the bearings, before then you rely on the additive package. Synthetic flows better at low temps (and in Canada some engines go bang with poor oil, others have a temp sensor which will restrict max rpm).
Low annual mileage is often lots of short trips. Lots of short trips means the engine spends most of its time running in O2 sensor open loop mode, rather than closed loop. That is because the ECU is dumping more fuel in to 1) get the engine warmed up and 2) get the cat up to temperature. This tends to increase fuel dilution of oil, fuel washing of cylinders, increase water concentration in oil since it does not get hot enough (coolant gets hot fast, oil takes way longer hence coolant-to-oil heat exchangers above oil filters which use the hot coolant to heat the oil during warmup & vice-versa when the engine is hot).
Low mileage short trips are considered "adverse duty", there used to be two oil change specs in the manual - one for long distance driving and a much shorter one (50%) for adverse duty. So a 9,000 mile oil change interval could be 4,500 miles in stop-start winter driving where the engine never warms up.
The classic killer of old engines used to be sludge - lots of short trips such as 5-7 miles to work. With longer commutes this problem has reduced, but it can kill modern diesels with diesel particulate filters. They fail to regenerate sufficiently, the oil cokes up, and suddenly the oil pickup screen is stuffed, turbo or rod goes and the bonkers expensive engine is toast.
