Just recommisiong my RD after many years of being laid up. Most surprised that the top of the range synthetics are now in the region of £25.00/liter.  Is it really necessary to pay that much, when there are others that start at about £9.00/litre.

Like all things, you get what you pay for.

Fully synthetics while not available at the time the bike was made, will lubricate more efficiently and (in a 2 stroke) burn more cleanly leaving less residue and ash. They will also smoke less.

However if you are in the camp that believes that cos they didn't exist when the bike was made, then modern oils are "too good" or unnecessary, you can by all means run a cheap supermarket oil.

I would ask: Would you wear a 70's crash helmet cos they were considered OK in the day, or one built now that is made from high tech and better materials ?  Your head is still the same head yeah ...

After all, these things never blew or seized regularly back in the day on the crap we called oil then did they ?

..... Oh wait a minute, yes they did.  Crying or Very sad

Use the best you can, and the bike will be happier for it. Wink

The "fully synthetic oil will make your clutch slip" myth is also bollox.

A fully synthetic oil will NOT make your clutch slip - unless that is, said clutch is already knackered. They have friction modifiers to prevent exactly that happening.

The reason fully synth's are more expensive is because they have cleaners and additives (and actually relatively little oil) to make them perform better and stay in grade longer.

Those cleaners and additives cost far more then a bucket of crude does.

As back at the top - you get what you pay for  Wink

Synthetic is not required on these old two stroke machines.
I have run all my two stroke kawasaki triples on mineral oil.
Engine failure has been due only to lack of oil!

Chip fat not recommended!

If I thought I would benefit from anything I would take advantage of it.

Back in the mid 70's, helmets only needed to meet BS5361 (up to 76), which later became BS2495 (in 77). In those heady far off days, fibreglass was considered the very best. It was heavy and did not absorb shocks very well - but it was the best there was. Most of us used it in the certain knowledge there was nothing better.

Now we have ECE-22.05, ECE-22.07 and SHARP (plus the relevant Snell standards) They all came about because materials had improved and became better at the job they are intended to do. ie saving your noodle in a spill  Cool

Oil has evolved even further than crash helmets have, there is actually very little (if any) mineral oil about now. Even the cheap supermarket junk has additives in there of some sort. Even if they are few in quantity and low in quality, they are still in there.

Modern synthetics protect far better (just like modern composite helmets do) lube better and leave less deposits in combustion chambers than cheap oils, so stubbornness or not understanding  the benefits aside, why would anyone NOT take advantage of that protection ?

I would no longer ride a bike in sneakers and a piss pot lid. I also do not run my bikes on the cheapest oil or chains, or tyres I can find either. I did back in the day mind.

Now, I use what time and technology has given me and buy the very best I can afford.

Doing any less is a false economy. You may get away with it when you do an odd jaunt every other weekend, but sooner or later, the inevitable catches up and the price has to be paid for using less than the best.

Don't be tight, engage brain and think about it.  Very Happy  Very Happy

Today's technology in yesteryears machinery gives the best of all worlds. Spend more time riding and less time repairing.

Semi sympathetic Putoline TT light 2T oil in my Suzukis. Better than the 70s era stuff and still reasonably priced.
Fully synth gearbox oil does make the clutch slip and that area still gets 20w50 as specified by Mr. Suzuki. Change every year (or 2500 miles) without problems.
Full synth does have friction modifiers - it's more slippy. Not recommended for running in an old 4 stroke as the bores glaze and the rings don't bed in properly.
Sometimes it's a waste of money getting too modern in these old tech engines, that said good quality oil is better than the cheap stuff.
