With a top shelf synthetic oil, the benefit of improved fuel economy, increased power, reduced emissions, reduced engine wear, lower engine temperatures, an internally cleaner engine, easier winter starts, a vehicle that runs "like new", for a longer period of time and reduced maintenance costs, apply to any vehicle, regardless of mileage on the vehicle. In twenty years in the synthetic oil business, all of my customers have reported only benefits.

Millions of vehicles come from the factory with synthetic oil in their engines and no oil burning issues at all.

Over 20 years experience in the automotive repair industry and 20 years experience in the synthetic oil business. Today's modern vehicles are equipped with piston rings that seat at virtually the first turn of the key. Can't have brand new cars causing pollution or the environmentalists would have a coronary!

I have no doubt that's true. But in this case it was not the best thing to do. I don't care about your "Over 20 years experience in the automotive repair industry and 20 years experience in the synthetic oil business.", I'm telling you what happened. Synth DID NOT work in this case. I also use Amsoil in a Honda motorcycle I had, it ran out of every seal and gasket. That bike NEVER had a leak until I used synth oil in it.

I use M1 in my G, I think it's one of the best out there. I waited till 10K before I switched and I use less than a half a cup between changes (7500mi). I am thinking of switching to Amsoil next change. So don't think I'm down on synth oil.

I will also bet that more than 90% of mechanics will tell you NOT to use synth in the first break in. Sure it may work, but 100 years of using it in engines must count for something.

 

Just because someone can turn a wrench doesn't mean they are up on the most recent technological developments. Millions of cars the world over come from the factory with their engines crankcase filled with synthetic oil with no problems, only benefits.

But does the G35 or 350Z?

IMHO, what's the hurry to change to synthetics? Even 10k is like 5% of the total operating life of these engines.

 

I would like to see that oil test...anyone have a link?

 

oil analysis

 

What oil test do you refer to?

Sitting down? The conclusions drawn from their oil analysis tests are invalid.

Many factors affect the outcome of oil analysis tests and as such can only provide usable information for the vehicle the oil sample came from, only. Any oil analysis laboratory will state this.

[QUOTE=HiTechOilCo]An extremely thin oil would show a horsepower increase, but that doesn't mean it's going to help prevent wear and tear better than another oil could. Indeed, 0W-5 oils are used in race engines because of the power increase they offer, but no one in their right mind would use that on the street.

A common characteristic of any brand synthetic oil is that it will increase power, so for a synthetic oil to be marketed on the promise that it will increase power is like saying, "Our tires are round and roll, so buy our tires!" Give me a break.

i didnt switch weights of the oil still using the oem reccomended 5w30. and i never specifically said that it was the royal purple that gave me the percieved increase in horsepower. because me and my ten years of wrenching says that its probably mostly due to the fact that i had oil that has been used and abused for about 3,500 miles and im putting in fresh new oil. be it synthetic, dyno bones, or the b.s. wal-mart recycled oil. but since the royal purple oil change my car definatley runs smoother. coming down a hill when im in third gear at 4k rpms the car is smoother. before at high rpms i felt the harmonics in the motor through the chassis, now i dont. when i wind out a gear all the way to red line its smoother. sitting at a light idling, its smoother. either way, i like royal purple. now continue to sell your product accordingly sir.

My point was that an oil increasing horsepower might not necessarily be a good thing and that it might be increasing horsepower because it is a very thin oil, sacrificing long term engine wear. There are, "thick", and, "thin", 5W-30 oils.

So it was, "perceived", not proven?

Oil can actually increase in viscosity as it accumulates mileage, so what started out as a 5W-30, can thicken to a 10W-40, or even worse. A thicker oil will decrease power, so changing the oil to the faster flowing/less drag 5W-30 can indeed increase power.


.

Again, as any good performing synthetic oil should also do. If you'd like to really see something, contact their technical services department and ask them what the HT/HS, (High Temperature/High Shear), test results on their oil is. You might be surprised with what they tell you. Most all companies proudly post this information at their web site. The HT/HS test is a test that measures an oil's ability to protect an engine under high temperature/high shear conditions, as with high performance driving, or taking a long summer vacation trip with a fully loaded down car, etc.

A vehicle that has the same engine. And you might be right if this was the only test. But that forum has the benefit of 3rd party testing AND the benefit of shear number of tests over multiple vehicles.

But continue to try to descredit their info. Even better, go over and post. I'd like to see that conversation.

 

using syn oil as an excuse to spend lots of time between oil changes is a bad idea, IMO. 4750 isn't too terrible but good lord don't buy into this 15000 mile oil change stuff.
Whoever is telling you that they don't recommend synthetic oil is an idiot that's just trying to jerk you around. If you buy a V12 Benz roadster, it'll come with Mobil 1 syn from the factory. Most high-end engines are broken in before you even get ahold of them anyway, I'd imagine that's the case with the VQ, but I could be wrong.

 

Many years ago (1973), my cuz and I too the tour of the GM plant in Arlington TX. Way cool. The one thing that surprised me was the what happend at the end of the assembly line.

3-4 gal of gas and a crank. Move it to the dyno. then a FULL TROTTLE RUN for at least 1 to 1.5 minutes! If it blows up, send it to the back. If it don't, send it to the showroom.
