Midnight Posted June 8, 2008 Share #1 Posted June 8, 2008 I have been using Yamalube 20W40 in my 07 Venture. I know there are other options but I decided I would use it a least for the first few years in case I had any warranty issues. I went to the yamaha dealer the other day to pick up a gallon of oil for my next change. Apparently 20W40 is not available anymore. They now have 20W50 instead. I asked why they changed. Dealer was not sure. Anyways I have a few questions that I was hoping some of our members could comment on. 1) Does anyone know why they changed? 2) I have 2 litres of 20W40 left over. Can I mix it with the 20W50 on the next change? Thanks Jim Link to comment Share on other sites More sharing options...
eagleeye Posted June 8, 2008 Share #2 Posted June 8, 2008 Mix it and don't worry about it, and when it's gone, use the 20/50 Steve Link to comment Share on other sites More sharing options...

Probably true anyway. I don't think you would have any trouble mixing the two different weights especially if they are the same brand. I've probably done worse.

But, who said 20w40 was no longer available, I just Bought 20w40 no problem. Link to comment Share on other sites More sharing options...
treeman Posted June 8, 2008 Share #6 Posted June 8, 2008 i use 10/40 & one QT of 20/40 but did not here about no more of 20/40 Link to comment Share on other sites More sharing options...
flb_78 Posted June 8, 2008 Share #7 Posted June 8, 2008 I would probably mix them. I don't use motorcycle oil though. I use John Deere 15w40 right now because I can get it at a really, really good price. I also use an automotive filter, Purolator PureOne PL14610. Rated as the best filter that will fit most Yamahas and Hondas. http://www.calsci.com/motorcycleinfo/Filters.html#OilFilters Link to comment Share on other sites More sharing options...
timk Posted June 11, 2008 Share #8 Posted June 11, 2008 Yamalube is a mixed oil, semisynthetic, unless I'm confuse. Link to comment Share on other sites More sharing options...
Sleeperhawk Posted June 11, 2008 Share #9 Posted June 11, 2008 My Dealer says 20w50 is now being used in the RSV and I have been using 20w50 from almost day 1 when I change oil. Link to comment Share on other sites More sharing options...

Guest Saddletramp Posted June 12, 2008 Share #11 Posted June 12, 2008 Yamaha is marketing a fully synthetic that carries a viscosity rating of 15-50. It is kind of pricey comparing to other non-specific brands but I use it regardless. Link to comment Share on other sites More sharing options...
Sleeperhawk Posted June 12, 2008 Share #12 Posted June 12, 2008 What "brand" oil do you use George? Mobil1 Motorcycle specific that I can get at Autozone. Link to comment Share on other sites More sharing options...

bobcat Posted June 20, 2008 Share #15 Posted June 20, 2008 Mix it and don't worry about it, and when it's gone, use the 20/50 Steve I agree completely.....I've put well over 150K on first gen 1300 Yamahas...I've used Castrol GTX 20/50 the whole time with no problems.....good stuff Link to comment Share on other sites More sharing options...
Poledar Posted June 20, 2008 Share #16 Posted June 20, 2008 Here is yet another option. I have used Spectro Golden 4 ever since I bought my '84 First Gen new, through my '88, now in my '86. It smooths out the shifting CLUNKS, and helps the engine run a little cooler. It's a blend of synthetic and petroleum and works wonders. I had to have it brought down from NY, and of course got a great price on it there. Poledar Bill Darling... Link to comment Share on other sites More sharing options...
heatonmt Posted June 20, 2008 Share #17 Posted June 20, 2008 My dealer says 10w40 is what to use now someone else's dealer says says 20w50 which way should we go? Link to comment Share on other sites More sharing options...
MAINEAC Posted June 20, 2008 Share #18 Posted June 20, 2008 Yamalube??? I wouldn't use that crap in my Cub Cadet.. Get some good oil... Mobil1, Amsoil Synthetic.. Castrol.. Benray.. Link to comment Share on other sites More sharing options...

Kirby Posted August 14, 2009 Share #20 Posted August 14, 2009 :grandpa:Just throwing my 2 cents worth in. I've used Mobile 1 fully synthetic 15w-50 in my Vmax for over 2 years (36,000 miles) with no problems. When just bought this new 2009 RSV I started using the same in it. So far, after 2 months and 6,500 miles, no problems. Just make sure whatever you use don't use "Energy Conserving" oil. Link to comment Share on other sites More sharing options...
