Synthetic oil?
I have a 94-95 gsr. It's running 10-30 castrol in it now. I like to rev somethimes, more then others. Should I switch over to full synthetic?

Re: Synthetic oil?
but since the only place oil is burned is through the rings, i can't see how 2 oils of the same viscosity could slip past the rings at different rates. or maybe the synthetic sticks to the walls more? i dunno.

Re: Synthetic oil?
However, since Honda specified a 7,500 mile interval on conventional for the car, I'm not entirely sure I'd risk a longer one.

Re: Synthetic oil?
Haha. Are you saying that just to say it? Do a search and let me know what you find. When people switch to synthetic, they get more oil leaks, and it burns off faster as well. With both being the same rated viscosity, the synthetic is thinner.
I agree. Unless the manufacturer specifically calls for synthetic, it's generally a waste of money.

Re: Synthetic oil?
Synthetics do not "cause leaks", do not "burn off", and are not "thinner".
Anybody can post to the Internet, and anybody does. The fact of having been posted does not lend any post any sort of veracity.

Re: Synthetic oil?
Hi,
I have heard plenty of horror story's when synth's first came out. Basically all the oil leaking out the engine and the engine burning up. I also remember hearing that if you started a brand new car with synthetic oil the chances of this were less then if you changed later when the car was old. I think they also sell a half and half oil that suppose to provide the best aspects of mineral oil and synthetic oil.
If it was me i would see what your owners manual says about it. If the manual says okay I would then call up a service writer and ask him if he see's any cars come in with problems because synthetic oil.
It has survived on the retail market for a very long time so im guessing they may have gotten the bugs out of it.

Re: Synthetic oil?
Thanks dad, but I've known about that site for quite some time.
When you switch from conventional oil to synthetic on an older car, it could start leaking in areas where the conventional oil was too thick to go through. It's not that the synthetic oil causes new leaks per se, but that the wear that was already there is enough for the synthetic to go through, but not the conventional.

apparently not. you have been drilled with misinformed information...
just to help you get started...a oil's thickness is based on it's CST 100 number, not whether it is synthetic or dino.

Re: Synthetic oil?
Hi again,
I just remembered that on a new car the rings wont seat if synthetic is used within the first 3000 miles. Only mineral oil will properly seat new rings. I guess the consequences of changing to synthetic before this mileage would be excessive oil loss from blowby.
I also heard they say now that you don't have to keep a new car below 50 miles per hour for the first 500 miles. I don't believe that you should drive faster than 50 for the 1st 500 miles, so don't buy into not doing that !

a 10w30 conventional oil is the same viscosity as a 10w30 full synthetic. same pour points. they would both leak at the same rate

Re: Synthetic oil?
pretty sure that interval is outdated. conventional oils of today have a much higher level of detergents than they did in say the 90's and therefore must be changed more frequently

Re: Synthetic oil?
i think you're having trouble grasping the concept of oil pour point, ie viscosity. an oil's viscosity is not discriminant of it's chemical make up.

Re: Synthetic oil?
You sure do make a lot of deep, insightful posts around here.
I never said anything about how an oil's thickness is determined, so I'm not sure what your point is.

Re: Synthetic oil?
You could go on and on about this topic. There is so much miss information out there about conventional vs. synthetic oils. With my experiences i have had cars that love the synthetic stuff like my RB25dett swapped 240sx, my current dc4, and my 2010 accord But i have also had cars that hated synthetic like my 240 with the ka24de motor in it, my old explorer, and my old suburban. And why this was IDK the only car that i knew why it hated it was in my 240sx.

Some people have a tendency to confuse symptoms and causes. Just because B follows A does not mean A caused B.

Re: Synthetic oil?
well, to be fair, i did say leak not burn. but i get what you're saying. and it still means that there should be no discrimination between synthetic and conventional as far as it's consumption goes.
