syntec blend

Shouldn't be a problem at all. I am running Syntec blend 5w-20 in my 04 Accord, although this has low miles yet. I wouldn't worry about it, Syntec blend is a good compromise between synthetic and standard oils. I also switched a vehicle over to full synthetic with high miles without a problem.

I recently changed two of our 200K+ mile cars (one is an '85) over to full synthetic and had no leaks or other problems.

you also get a higher milage per oil change. Syntec or syntec blend oil retains its lubricating and protective chracteristics 3-4 times longer than regular one. I've been using semi-syntec Castrol for the last 5 years with with 15-20 k changing period. Never had any problems.

I've been using Mobil 1 5w30 in my 2000 Civic SiR for 50,000km now. It doesn't leak a single drop.

2 things, going longer then normal between oil changes just cause your using synthetic is NOT a good idea

To qualify as "synthetic blend" all you need to do is put SOME synthetic oil in it. So technically it could be plain oil with 1 drop of synthetic oil added.

If you want synthetic, then get 100% synthetic oil

I don't know about an odyssey, but my neighbour has a 86 accord with over

500, 000KM on it, and still going strong

WHAT?! They put a sticker on a windshield suggesting an oil change interval of 15,000 miles?! That is stupid and I don't care what kind of oil it is. Generally speaking, under normal driving conditions, you can expect dino oil to go 5,000, maybe a little longer.

Semi-synthetics start to deplete their pack (TBN) around 7500 miles and although some synthetics say they can go higher, I have seen used oil analysis reports suggesting synthetics should be changed at no more than

10,000 miles. With severe driving conditions (heavy towing, cold start/short trip driving, dusty conditions, etc.), these figures would be much less.

Going 15,000 miles on this oil is a recipe for disaster. I don't doubt it can be done since you will rejuvenate the oil by several top-offs during this period but at what cost to the engine? If it were me, I would change this oil after 5,000 miles, send in for an oil analysis report (about $40) to Amsoil, Blackstone or some other well established lab, and look at the results. I bet you will never see a professional lab analysis recommending this oil to 15,000 mile intervals.

It is an excellent quality oil and can mix and match with conventional oils without fear.
