Switching back to Conventional Motor Oil???
The last time I took my 95 SC300 in for an oil change, the dealership charged me $78 for it becuase they used full synthetic oil. I only have just under 100K on the engine and dont really feel like spending that much every 3-4K for an oil change.
I'm just wondering if there'll be any damage or downside to switching back to conventional motor oil or maybe even a synthetic blend?
Thanks in advance!!!

I would stick with full synthetic. You might want to change it yourself, it only costs about $30.00 and it's not that hard to do. I leave my synthetic in for 5K and that's being pretty conservative, I wouldn't change it every 3or4K.

Here's some advice, stop going to the dealer. If you need an oil change, you can learn to do it yourself OR at the very least take it to a lube shop where you can get an oil change with full synthetic for $40-50, some places less. Most lube shops will do it right, changing oil is not difficult.

I go 5k between changes with only full synthetic, sometimes do it myself but it is a pain on the RX. If you take your own synth. to the dealer as I have to do at least tell them you want a credit for the oil they'd normally use.

Syn's a waste
Contrarian point of view here, but the forum is a good place for exchange of ideas. I would not be so gung hoo to jump on the syn band wagon. I believe that you'd be hard pressed to find that the expense of syn to be worth a measurable difference at this point in the engine's life. It's ~11 to 12 years old now, the beni's of full syn would have been more evident if used from its earliest years to present. Also, case in point, it is in the great condition 11+ years later running non-syn.
Regular oil changes at 3k intervals of high quality, brand name (non-syn) oil and purchasing a high quality filter (TRD, Mobil One, K&N ) would make as much a useful contribution to the life of the engine. Also, I think that there are huge differences in oil filters that people never consider. Putting a poor quality filter on your car is probably a much bigger deal.
The 2jz is such strong and well built engine it is hardly pressed in a stock capacity running 225 hp. As many of you know, the stock internals of this engine easily handle tubo applications pushing 600-800 hp. It's on a vacation in the oem form of the SC300 handling the duties asked of it.

IMHO, don't waste your money on syn, your engine doesn't need it now, spend a little more on quality filters. (I'm going into my bunker and putting my helmet on, lol !!)

if you want to go synthetic blend, blend the oil yourself so you'll get 50/50 mix. most synthetic blend oil on the shelf only contains 25% or less synthetic oil.

Say in the case of an emergency, on the road and your idiot light comes on....the only oil available is conventional but you always run synthetic. Would it be a BAD BAD idea to add a quart of conventional to avoid driving on the idiot light until you can buy more synthetic and do a full oil change?

to answer your question, NO, it would NOT hurt it a bit.
As a matter or fact, If you had been running 5W-30 and the only oil you could get is 10w-30 (or vise versa) that won't hurt it a bit either.
