that was deceiving, i thought it was full synthetic. pass for me.
semi-synth just means it breaks down faster.. so just need to change oil sooner than full synth (every 6 vs 12 months)
That basically means it costs double the price if what your saying is correct.
It's more than just longevity, a good fully synthetic oil with up-to-date certifications has substantially better characteristics all around between wear protection, temperature management & longevity, cleaning/detergents, start up protection, maintaining advertised viscosity, etc.
Engines will usually outlast the rest of the car anyways, or people sell and move on before engine wear is a concern. That being said I think it's far more prudent to just pick up those $30 5L fully synthetic oil deals that come around. You certainly reduce your risk of expensive engine problems and keep your vehicle/engine better maintained for its next owner.
Besides, for most people it's more important to keep their air filter fresh, throttle bottle clean and just work on better driving techniques.
@TrulyUnicorn: Thanks!
This might be a stupid question if I drive 3,000 Km a year do I still need to change the full synthetic engine oil (quite sure the answer is yes)
But I'm looking for a way out of it 😂
@Tehcookiemonsta: Oil mostly "goes bad" from the products of combustion, if you're only driving it 3,000km/year I'd honestly say you could stretch it to two years. Modern synthetics are very resistant to "shearing" and will stay stable for extended periods of time. Oil also darkens due to heat so even if it appears dark on the dipstick it would almost certainly be fine for 2 years.
It might be a good idea to get a decent oil filter if you want to go that long though. Ryco's Syntech line is great, so are Mobil M1 filters or the updated Fram Extra Tough's you can find on amazon. These synthetic filters last much longer and filter out much finer particles at greater efficiencies. I'll spare you the details but a good oil filter makes a difference and the extra $5-10 is a good investment if you want to go 2 years between oil changes.
@TrulyUnicorn: If a standard ryco or genuine filter is good for 10k+ then of course it will be good for several short duration oil changes over several years.
Synthetic Oil does need to be changed about every year as the additives start to oxidise. But with some of the oil deals available now its certainly cheaper overall, now, compared to when dino oil needed to be changed every six months.
Considering aluminium isn't magnetic, this seems like it wouldn't be any use except on a few parts like the piston rings (assuming those aren't stainless, which isn't magnetic either). Maybe it used to be good in iron block engines?
Where does it say this is actually magnetic? All I can see is them comparing the cling to a magnet?
All the cylinder walls, crankshafts, camshafts, and rocker arms that I’ve seen have been made of steel.
I believe it adds some Group IV true synthetic ester oils which cling to the engine. So yes, not exactly magnetic.
yeah i think "magnatec" is just a marketing ploy, as @mapax was saying.
an oil film clinging to surfaces isn't because it has magnetic properties. It's the formulation and additives that the fancy lubrication scientists (tribologists?) have added to the oil.
Semi-synth just fyi
