So you hate your car then? I rather like mine, so I'll stick to synthetic thanks.

I believe that the newer engines call for fully synthetic. Whereas older engines "can" use semi-synthetic. As I mentioned before in my dealings with air cooled motorcycle engines (Ducati). These engines need the highest quality engine oil to prevent breakdown ie foaming under demanding conditions. Synthetics are a definite NO NO especially with wet clutches and semi-synthetics are avoided when possible. I'll use the best non-synthetic oil possible. Not quite sure but some of the more exotic Euro and race cars do not use synthetic - there must be a ggod reason for that. Did any of the owners manuals recommend or require the use of synthetics for our car? The Mazda 3 and 6 probably do now, but not ours. I've also did the flash in the pan oil-additive thing years ago in other vehicles unsuccessfully.

Do I hate my car?........None in the least. Ten years with the K8 has shown me that I must have been doing something right.

for my k8 i use whatever i can afford, when i get ze or built de Ill only use synthetic, even on k8 i use good filter, at least napa or bosch. Fram is just plain crap

Curious as to your choices. I would have thought that Motul would be your first coice for all vehicles followed by Mobil 1? Motul would be my first choice if it was readily available.
Bikes? What kind?

As for the bikes Suzuki FXR150, the pub bike ?? you say well you can get
tanked and still ride the wee thing home in one peice, mind you don't
laugh it will do 90mph with me sucked to the tank.. Yea played with..

The big bike, Kawasaki ZXR750 getting traded this year carbon can
Dynojet needles K&N filter, speed way to fast, but a workout to ride
as ive got one hip pinned up from a old accident.....

The daewoo just does'nt like mobil 1 at all burn's it up where as the
castrol seems to last the distance till oil change time..

Obviously, wet clutches with a synthetic are a big "duh". But since we've got dry clutches, it doesn't matter. And why weren't syntetics recommended for our cars that began production in 1992?? Maybe because there were only one or two brands actually available in a consumer store by then, and they were ridiculously priced? I've used synthetic in all my cars since 1995 when the original formulation of Castrol Syntex was $5.50 a quart. I won't stop either. I'll use regular oil on break-in, but only because it'd be ridiculously expensive when I plan on doing 3 or 4 oil changes in the first 500 miles after my rebuild.

It's usually reccomended to use a non synthetic after a rebuild anyways. It just helps seat the rings properly.

Obviously most of this post is a matter of opinion. But from experience I put 300,000km on a 92 SOHC mx-3 engine using regular castrol. Didnt burn oil or nothing..ran like a champ. I think synthetic is a waste of money, especially in a 12 year old car that has had most of its wear on reg oil. All oils conform to the same standard.
I would only use in a car that came factory with it. We used it in our 98 corolla for about 4-5 oil changes and now we use mineral oil. The thing burns more oil even though its been well maintained and cared for. I blame the synthetic oil but could be wrong, Like I said this is just my opinion so dont bash me

thanks

I have heard that once you start useing mobil 1 you cant stop even after an oil change. Any truth to this?

I believe this is true since after switching back to regular oil in our corolla we were loosing a lot of oil. No blue smoke and no leaks which is weird. Before using mobil 1 it was full on the dip stick before changes.

Well then it looks like i wont be switching to mobil 1 anytime soon.

Never heard of that before.....but it doesn't mean that there's no validity to it either. The Mobil 1 - are we talking non, semi, or fully synthetic?

Just regular 10w 30.

OK, the non-synthetic, many thanks.

AFAIR Mobil 1 is always a synthetic. It's supposed to mean Mobils best or #1. Natural oil is just Mobil.
