Well over the years i have lost three engines to oil issues , My first was and engine i bought BEFORE i started doing the DIY thing . I bought a 390 Ford built by the guys that were suppose to be the BEST FORD engine builder . As a KID i had good money and i was still in the LEARNING STAGES of engine building way bqack then i gave 2700 US DOLLARS for this RACE engine . I installed it in my car and i put in the seven Qt.s of Kindell (sp) racing oil that came with the engine and we took it to the local drag strip on a Thursday evening , The owner of the local strip was old friend of my mom and my one cousin . He was out there testing his toy along with a few others . I READ and understood the break in instructions and i had made passes as per the instructions . All seamed well and it was NOW time for a full blowen flat out hammer down pass , they told me the engine was GOOD to 7K , i had the brandnew SUN two piece red line 7000 tach mounted on the steering column , i brought her off the line at around 5500 and a side step and took her to the 7K and hammered second yea buddy she was flying and took her on up and pounded third and just as i was cocking myself for the shift into forth the world came to and END and in a huge KERRRRBOOOM and a bright orange flash pieces and parts went flyen . That 390 exploded like a bomb went off big bumps in the hood and floor boards . There was NOTHING to save the largest part of the block was hooked to the motor mounts , the crank was now in three pieces head in two pieces layen on the track all three carbs were ELJUNKO .And today if you walked the east side lane with a metal detector i am sure you would find pieces and parts form 1964 . Something seezed up and something came unglued , Next engine that had issues was the cummins NTC 350 that came in my new 1977 I H 4300 and the problems started AFTER the first oil change . I went and bought a 55 gallon drum of Texaco USAR 30 weight series 3 to do the first oil change at around 6000 miles , New spin on and a new Lubrafiner dumped in 12 GALLON of oil and Monday morning at 3 Am we went to work , At 8:30 that night when we got in we pulled the dipstick and my NEW CUMMINS was a gallon LOW , welp being use to DETROITS they used a gallon a day even if ya did not run it so i dumped in a gallon and went home , next day when we get in it needs a gallon , HUMM my buddy's truck is NOT usen a gallon a day and it is the same truck smae engine , transmission, and rear ends only color and S/N are different . This goes on for several more weeks and we do the next oil change and it NOW time to take it up to Cummins to be PUT IN SERVICE , the PUT IN SERVICE is where they run the overhead and pull the injection pump and check and make sure that the fuel rate is correct as most times they are a little on the LEAN side and IF you know someone NOW is the time to get just a WEEEE BIT MORE . While i was there i was talking to Bobby a good friend of mine while his brother was running the over head and i said something to Bobby about the Gallon a day habit it had and Bobby says OH NO something is NOT right here you fill out the oil consumption report for three weeks and bring it back , amount used per day and mileage After three weeks i take the report up and Bobby looks it over an makes phone call and he was told to have me bring it in and they are going to do a tear down and REBUILD on and engine with just a shade over 20 K . So we lost four days of work and Bobby calls me and wants to know if i want to bring my own oil or have them put in what they use and he questions me over the true mileage and said to come up and look . So i run up and Bobby shows me my main bearings and rods along with the sleeves and pistons out of mine ,the bearings were starting into the copper the sleeves had scoring along with the pistons and he asked what i was usen for OIL and i told him Texaco Usar 30 Series 3 an he told me NO)T to use that anymore and to go either Shell or Deloc , i went Delo 400 in 30 weight as instructed , now had that been the BIG CAM then ya use the 15-40 , small cams straight 30 . Even after we went wacko on Building that 350 into a monster that would lay down MORE Hp to the ground then a KTA 600 turned up 20% did i still ran the delo 400 30 weight and at a shade over 400K miles when i had a piston go south the mains and rods looked almost new,. . The other engine that took a dump was a 460 Ford and it was my fault on that as i had poke a hole in the oil filter and almost ran it out of oil before i got back to the shop and the only OIL i had at the shop at the time was what was left of that drum of Usar and i dumped in a gallon and in the five miles from the shop to town i scraped out the bottom end of the 460 . Now for the oil of choice for our old cars and gas trucks has been Castrol I ran that in my 79 Ford F 250 4x4 and put 279000 miles on it before it got totaled from a head on then my 88 Ford F 350 with a 460 that one i put 278k on it and was still running strong when i sold it just upgraded to a Dodge with a Cummins. That one runs on Delo 15-40 series 3 .
