That be the stuff I use, but unlike you I have NO faith in the VRO on a JOHNNY-RUDE. I've seen too many fall with them hooked up. But I had to tear down my 140 once to replace a piston(broken cir-clip), the inside of the engine had a very nice oil film left on all of the internals. The one time I used GENUINE JOHNSON 2 stroke oil I lost 2 bearings in my 35HP JOHNSON. When I pulled it down there was no residual oil left, yet I know it had 50:1 run through it. I know that alot of shops call the PENNZOIL "piston scuff oil", but I haven't had any issues with it. I know over on SCREAMANDFLY they reccomend the PENNZOIL if you don't want to fork out the dough for ALLISON or KLOTZ.

no faith here on VRO but it's not the VRO that will kill your motor it's the voltage regulator / rectifier that will stop the tach from working which also runs your VRO so you are good as long as you have a tach but if the tach ever dies kill the motor asap you should be ok.

Re: walmart tcw3 supertech
 

my tach has been down for the last season and a half....motor runs perfect.....what-up??

Re: walmart tcw3 supertech
 

The tach signal is what tells the VRO to pump.

NO TACH, NO OIL!!!

Re: walmart tcw3 supertech
 

um you better chek that out asap as long as it's just the tach it's self ifyou replace the tach and it is working then you are ok but if you replace the tach and still dead you better just go to premix. you can run the tach off your yellow / gray wire on the rectifier but you can not run the oil injection that way.

Re: walmart tcw3 supertech
 

it's just the tach that's on the fritz, pump itself is fine

Re: walmart tcw3 supertech
 

easy to test just take a 12v test light and with out starting motor turn it over with the light hooked to the gray wire to the VRO pump or the gray to the tach it your test light pulse's then you are good to go.

Re: walmart tcw3 supertech
 

OK I owned an Auto parts store for 15 years sold it to Carquest in almost all cases privet label parts and oil are the same as the name brand sometimes the name brand has different grades of the same part then it hard to know which grade you are getting in the privet label as for warranty a product that meets the OEM specs can be used but is it worth the hassle if something goes wrong if the dealer tells you they won't warranty something because you used brand x check with brand x they may go to bat for you and get the dealer to back down hope this help confuse the issue for everone

Re: walmart tcw3 supertech
