Customer photo review of 8007-012 Advanced European Performance Full SAPS 5W-30

Michael W.

I’m retired Service Pipefitter Local 533 in KC,MO. I started using Schaeffer after attending a trade show I was talking with a representative from Schaeffer’s asked him if they had oil for 1999 Harley Davidson Superglide his reply was “Yes” it’s now in my 2003 RoadKing with 68k miles and my 2016 F150 2.7tt motor with 85k miles. This all Started in 1999 haven’t looked back since, great product it works great!

I was introduced to Schaeffers products as a heavy duty Mechanic at an international Tour company. We used and abused those machines. Even with the abuse these engines were running over a million miles without missing a beat and it is due mostly to Schaeffers products. From oil to grease those machines kept rolling down the highway. So I began using telling everyone I could about Schaeffers. My dad began using it in his 2017 ecodiesel and picked up 3 more miles to the gallon. I began using it in...

Well I have been using schaeffers oil since I bought my pickup back in 2006. It had been good to my truck for years and here we are goin over 100,000 miles and keeps working just great. I have no complaints about the oil.

Use Schaeffer oil in my 6.7 powerstroke. My truck is only used to pull a 16k trailer up and down the east coast. Have oil analysis done at every oil change by blackstone labs, results are amazing. Have used in my 1999 7.3 powerstroke also with outstanding results. It’s worth the money in my opinion, just wish it was easier to source locally.

I first used Schaefers methanol oil for my racecar. That made me switch from Amsoil to Schaefers in my daily drivers and customers cars. Hands down the best motor oil.

I’ve been running schaeffer’s in my trucks and equipment for the last 8-9 yrs. Always great products, haven’t had an oil related failure since. My duramax is pushing 330k!

I use schaeffer oil every time I do my oil change on my 2004 Toyota Tacoma. I was driving pretty far for work at my last job so the 12 qrt case came in handy. I usually do it every 6k, but I know I could do it every 8k if I wanted to.

Randal R H.

I first began using your oil in my 2012 Harley Ultra Limited. The bike improved as suggested with amazing results. Especially on the second service after the initial cleansing. So, I figured I would try your Advanced European blend in our Passats. Holy mother of pearlesence! Again, on the second oil change, the 2017 Passats both smoothed out and also yielded increased mpg! My cousin started using these oils in his diesel truck and the mechanic said it was tje cleanest engine he had seen and aske...

Bought a 2018 Lexus ES 350 - 3.5L V6 ~ 270HP, last year end of June with 108,000 miles on it. As I normally do my own oil changes I changed out for Schaeffer's Supreme 9000 0W-20 Full Synthetic and a Fram 20k oil filter. This picture shows my mileage after running from Wausau WI to Green Bay. Not bad for a 6 year old car with over 100K miles on it. I ran that oil up to 122,000 miles and it still showed amber/light green on dipstick and when drained the oil I could see through it. I kno...

I have a 2016 Toyota Camry with the 2AR-FE engine. It will not be getting any other oil besides Schaeffer's. I would highly recommend this oil if your engine has variable valve timing because of how clean this oil keeps your engine. You will pay a premium for this oil but if you want to keep your car a long time, it is well worth it!

I first encountered Schaeffer oils at a local tractor dealership. They were recommending Schaeffer Racing Oil for use in engines in garden equipment. I started using that oil in a 1942 Chevrolet and noticed a quieter engine and improved oil pressure. Began using Schaeffer 15/40 Diesel oil in my Cummins 6bt boat engine. By the dash gauge, the oil pressure in that engine improved slightly. Engine runs smooth and cool. Very satisfied with Schaeffer oils in both automotive and marine applications.

I love the Schaffer’s oil product that I purchased. It’s the best oil brand out there for the rugged abuse we put our racing engines through . Thank you for making a quality product!!! I will be purchasing more in the future.

Every one of our crane operators tried Schaeffer's Hi-Visc Boom Lube compared to another top brand and preferred it for its ease of use, effectiveness and efficiency! We buy it by the case now. Dale-Entrussed, LLC

I have been using Schaefer oil in everything I have. 20w50 race in my two old Harleys, 5w30 9000 in a 95 Explorer that gets 27 mpg. 15w40 race in a modified slant six (runs better on that then 10w30 7000) I recently bought a 01 GMC with the 6.0 and 289,000 miles.Even though it is clean inside indicating good Maintenace was a company truck, I took a 3200 mile trip with it using 10w30 7000 oil. The first quart was gone in 400 miles,the 3 spare quarts I took were used up by 1600 miles and I h...

My father sold Schaefer oil and I have used it in my personal vehicles. I switched my motorcycle oil to Schaefer because factory brand oil would not keep my oil pressure up.

So glad to now have an option that meets the specs for my Ram TRX. My first oil test showed low viscosity for the factory fill after a couple thousand miles. Will test this in 6 months to see if the viscosity improves; looks like a high-quality oil.

This stuff really works. It actually bonds with the ball joints and stays there, as well as truly keeps water out of the shield (unlike other marine grades i've used), while of course conditioning the shield & bushing urethanes.

I have been using Scheaffer Products for 20 years and it has proven to be the best over all others. I have had magnificent results from grease,oils,fuel additives,cleaners,penetrating oil and some others. I highly recommend trying Scheaffer products you will see the difference in performance and pricing.

Have used Schaffer products for several years, including oil, grease, diesel fuel treatment, and even cotton picker spindle grease. I am now retired but bought through Rock Ridge Farms Partnership. Have never had an issue with any product, and believe the quality is second to none. Currently using in a 3.0L Duramax in a Chevrolet truck.

I'm pulling a 42' 5th wheel with my 2025 RAM 3500. I changed the oil at 800 miles, and the difference was noticeable - the motor idled smoother, it was quiet. Its loving the new oil!

I 1st learned about Schaffer products about over 10 years ago. I was the head mechanic on a custom harvesting crew that had a fleet of about 20 Semi trucks, and over 20 trailers. I was inspecting the driveline on one of our trucks during a routine maintenance. I noticed the truck had 1 Ujoint with just a tad bit of play. We were in a time crunch and didnt have time to replace the Ujoint. One of my co-workers suggested I get a tube of Schaffer grease and try on that Ujoint until we got the time t...

I have used your oil for years and it’s the best oil I’ve ever used also your other products like your grease and spray lubricants are the best I’ve ever used. I use your products on my dirt track race car and I absolutely love them. The funny part is that most people have never heard about Shaffer oils here in Oklahoma . I would be proud to have you sponsor me with your products for my car and get you better known around this area.

I have used all trans in my 98 k1500. It currently has 250000 mi and still works great. I also used it in an old truck th400 that had metal in the pan. And she's still pulling trailers. I'll never use anything else.

Have used their oil in other vehicles and was hopeful the otr 10w-30 for my 2012 f-350 would work just as good. It ran smoother and noticed the diesel nock when starting isn’t as pronounced.
