highest miles test: regular vs synthetic

[sblvro]

<150,000 miles >200,000 miles
Regular oil
Synthetic oil


as proof positive which oil really give results, please post if you have used regular vs synthetic oil and up to what mileage your original engine lasted

Sorry - but what does this "prove"????



I really doubt that there are too many people here that have worn out a modern engine - and if any have, the chances are quite small that it had anything to do with wether they were running syn or dino.

Just my .02

synthetics have been around for some time and not just for the modern engine but previous experience with synthetic use and how much miles before the engine died. mechanical problem is a variable but can be eliminated.

How modern is modern? I put 160,000 plus on an '85 Volvo 740 using dino changed every 3000 miles, and 170,000+ on an '89 Toyota Tercel using dino changed every 3000 miles. My dad, and later others in the family, put 340,000+ on a '74 Toyota Celica, changed with dino Castrol every 3000 miles.

In all my 31 years of driving, over too many vehicles to count, I've never had an engine failure (does having to replace a head gasket on a '71 Datsun B1200 count?), much less one that could in any way be attributed to oil. On two vehicles, the rear main seal went- a '79 VW Rabbit, and a '93 Ford Ranger. The Ranger's was an acknowledged manufacturing defect, corrected by Ford with a TSB; I argue to this day that the VW's was a manufacturing defect as well.

Proof of anything, nah; fanning the flames of the oil war, yah.

And? Like I said - this proves nothing.

IMHO, synthetics are a waste of money in a modern engine for 99% of the use most of us will ever see. Change your oil regularly with any good quality oil and our engines will virtually never have an oil related failure.

the reason for this thread is the contention by one synthetic oil manufacturer that with its use, there was no sign or only minimal wear of engine parts even at 200,000 miles. oil seal failure is also significant because some oil seals are not compatible with synthetic and vice versa. comments are good but at least participate in the poll and let's see if it is really worth it, to go synthetic, that is!

Heck, I've always buy a new vehicle at either 100,000 miles or 3-4 years, which every comes first.

So why worry about what engine oil to use.
