wildebill308 Report post Posted March 11, 2016 I use Rotella T-6 and was happy to see they are running their $5.00 a gallon rebate program again this year. You can find out how to get the rebate on their web site. http://rotella.shell.com/promotions/synthetic-oil.html#iframe-L2RpeS9zcHJpbmcxNi9PMTE2MC8= Bill Share this post Link to post Share on other sites
huffypuff Report post Posted March 11, 2016 Walmart is $12.97 a gallon - $5.00 is $7.97. Free shipping for 6 gallons since it will be over $50.00. I wonder if you have to get a separate receipts for each gallons or only get a rebate for one gallon per household? Almost sounds too good to be true to me. http://www.walmart.com/ip/14958327?wmlspartner=wlpa&selectedSellerId=0&adid=22222222227009452554&wl0=&wl1=g&wl2=c&wl3=40839554912&wl4=&wl5=pla&wl6=52987236446&veh=sem Share this post Link to post Share on other sites
wildebill308 Report post Posted March 11, 2016 Unfortunately the rebate is on T-6 and T-5. Bill Share this post Link to post Share on other sites
kaypsmith Report post Posted March 12, 2016 Yep, synthetic only, 21.96 per gal on Walmart website. Although you can get the coupons for 1, 2.5, or 5 gallon, and it states $5.00 per gallon. Share this post Link to post Share on other sites
manholt Report post Posted March 13, 2016 If the $5 per gallon is for real, then it would be worth keeping 10 gal. in garage! Carl Share this post Link to post Share on other sites
jleamont Report post Posted March 16, 2016 I saw these at Wal Mart last night for $12.97 per gallon just as Puff listed above. The rebate fine print only allows up to 4 gallons per household to get the rebate. Its tempting to switch over from Mobil to save a few $$ Share this post Link to post Share on other sites

manholt Report post Posted March 17, 2016 Loves has T-5 for 17.95 Share this post Link to post Share on other sites
wildebill308 Report post Posted March 17, 2016 From what I was reading in the fine print it only goes to 4 gal per person on the rebate. Bill Share this post Link to post Share on other sites
wildebill308 Report post Posted April 14, 2016 Well here is an update. I just got $20.00 in the mail from Shell. I am also extremely happy with my oil analysis results using T6. All the results were at or below the universal averages. My TBN was 6.8 This oil only has 6100 miles on it I could run this oil another 10,000 miles (this would have put me in the ballpark for the 15,000 mile change interval recommended by Cummins. I will try to get more miles on this new oil this year. Bill Share this post Link to post Share on other sites
jleamont Report post Posted January 12, 2017 So my oil analysis just came back, I am scratching my head as it looks like I changed it prematurely but it had 14,000 miles on it . I dumped all of the motor oil in the generator and Coach engine prior to parking for the winter. Photo below; Share this post Link to post Share on other sites
manholt Report post Posted January 12, 2017 With a couple of exceptions, it looks like my Vitamin Pill description! Nice report card, too bad you dumped it... Carl Share this post Link to post Share on other sites
wildebill308 Report post Posted January 12, 2017 Yes that is a good report. What was your TBN numbers? What lab did you use? Bill Share this post Link to post Share on other sites
jleamont Report post Posted January 12, 2017 NAPA, I have no TBN since they asked for a virgin oil sample to compare. Since I flop between Mobile Delvac (in the sample above) and Shell depending on the best deal. Share this post Link to post Share on other sites
manholt Report post Posted January 20, 2017 Since I have never had a MAC engine, do they run on Rotella T-6 also? Probably a dumb question. Carl Share this post Link to post Share on other sites
jleamont Report post Posted January 20, 2017 Yep, we use Rotella T5 at work, 10W30 Diesel in everything. Share this post Link to post Share on other sites
