I use Mobil 1 full synthetic. You should too.

 

Actually, viscosity is a measure of how "thick" or "thin" a liquid is.. I think you're confused.

 

Particle sizes is what he's referencing. Most synthetics use smaller particles. This causes them to effectively not stick to everything, and the agents help it to do just that. It forms more effective boundary layers and such.

However, Mobil 1 is an exception. It was called "tri-synthetic" because it consisted of 3 different sized particles. It was also one of the only synthetics you could run effectively in a used engine for a long time, due to the increased wear and gap caused by regular oils.

IF you changed from regular to synthetic (at the same viscosity), and saw a 15 psi drop in oil pressure, all I can say is that regular oil was caked on pretty heavy, forcing it to have to put out a lot more pressure to create the same oil delivery. Kinda like your arteries on a diet of high cholesterol for a few years.

Synthetic base stocks are actually more true to the viscosity, and they react better to the expanders, giving them increased thermal breakdown, and wear intervals. They should actually show better pressure, as a general rule, especially once hot!

 

Ah. What he said makes sense now. Thanks for clearing him up.

I always like our discussions, they're fun.

 

you guys get too technical for me sometimes.

 

U know thats actually da 1 that I use, but I was planing on switching to Royal Purple.

 

Another good explanation, thanx a lot man....

 

AMSOIL, other synthetics are crap (btw mobil 1 is not what it used 2 be but still a good synthetic). I run it in my sr20ed 240 which was previously running mobil 1 and i got a noticable performance gain. Not only will you notice a performance increase but when I switched to amsoil 10w30 in my truck from the previous owner using penzoil it immediatly got rid of the spark nock and the car no longer smoked. I did, however fix a major leak be4 switching over b/c amsoil is expensive if you let it leak out otherwise its very cheap to run considering its guarenteed for 25,000 miles. Amsoil puts almost all their money into the research and developement of synthetics unlike most companys and they've been doing it forever. Royal purple is decent performance wise but it has been known to cause premature cylinder wall wear/heat scoring. As far as non-synthetic oils go; they're good for breaking in a motor and stopping minor leaks (because all the crap thats in them clogs the gap where ever the leak may be) but they don't even hold a candle to synthetics

 

Thax a lot for the help, now i have a better concept of synthetic oil.. thanx again
