I always have to laugh at the ignorance of most people when it comes to
Synthetics verses dino.Do you guys have a clue about all the different
things oil has to do????
Before you make ignrant statements like it won't have any effect on
longevity READ SAE reports, READ FORD motors reports from 1976 on Mobil
1 READ about the difference in shear rating and ability to hold
viscosity and the difference in detergence.
Which reports, where are they and what is the report or reference
number? What is detergence? Is that anything like detergents?
And shear resistance, viscosity stability and detergent capability
doesn't necessarily affect longevity of the engine. Only if you run for
very extended oil changes such that dino oil has pooped out will this
make a difference. And with modern dino oils, that is a long time and
many miles.
I'm a big fan of synthetics and they have many advantages, and I believe
an engine will last longer using them, but I have to agree with the dino
folks that given frequent changes (5-7.5K) modern dino oil will take you
to probably 200K miles. If you plan to drive your car for 500K miles or
run 10,000+ change intervals, then synthetic might begin to some some
good advantage.
Clay seems to be one of the few who isn't talking out of his ass or
just giving opinion.
And you aren't one of the few.
I have used synthetics since 76 Mobil 1 Redline synthetic gear oils and
tranny oil.I use Shell Rotella Diesel synthetic now (cheaper than Mobil
1 But I do use the synthetic filter from Mobil1.
Good idea. I've used synthetics since about that time frame also, but
I'm aware of what they add and don't add. They add greatly to cold
start capability (especially at temps below -20 or so). They are better
in extreme heat, but that isn't a problem where I live.
My gas milage on my vehicles has alway increased with the change to
synthetis and I always get better than EPA estimates.
I have my oils tested on each vehicle when new to provide info for
warrantee protection.I use synthetic in all my bikes (22) my Accent and
my Nissan Harbody. All have Redline synthetic inn the tranny AND rear
ends.
Changes in fuel mileage are not enough to measure in normal driving and
conditions. You'd need very controlled conditions and very good
instrumentation to even notice a 2-4% advantage. This is the placebo
affect at its best.
I'm sure my post will offend some of you but I'm sick of hearing
ridiculous statements with no basis in fact.Don't take my word for it
READ THE FACTS.
You have provided no facts nor any references to facts.
Besides what do I know,I retired at 45
Given your demonstrated literacy, all I can say is isn't inheritance a
wonderful thing.
