Re: Oil Filter Recommendation Reply #3 – February 16, 2020, 08:57:52 am Everyone should be aware of the quality differences between oil filter brands. Choosing the wrong one can cause real problems with your engine. You tube has several videos of the dissection of the different brands showing why some are good and others are not. Judge for your self after watching. https://www.youtube.com/results?search_query=oil+filter+comparison 1 Likes
Re: Oil Filter Recommendation Reply #4 – February 16, 2020, 01:46:39 pm Online oil filter reviews need to be viewed with a critical eye, especially garage floor demos.Construction techniques and materials are very important but just taking them apart for comparison does not prove how well they actually filter in real world usage. Long testing in actual vehicles, with periodic oil analysis or highly controlled laboratory testing would provide more accurate and useful information. While we never seem to see the results of this type of testing, it undoubtably is done by the auto manufacturers. The OEMs use the results of testing to specify the right filter for engine long life. If Ford recommends a certain filter for their engines, you can sure it is adequate for the application.Many of the premium filters are overkill with exceptionally long service lives, 10,000 miles or more in some vehicles.Most LD owners change oil and filter every 3000-5000 miles. I have run Mobil 1 or Purolator Pure One filters for many years, after they showed to filter well in long-term oil analysis on the fleet at LAX. Walmart usually has the best prices on oil and Mobil 1 filters and the Pure One filters available across the street at Pep Boys.Oil can sometimes sell for less at Costco, during sales.Larry 2 Likes
Re: Oil Filter Recommendation Reply #5 – February 17, 2020, 11:37:17 am Having an engine oil analysis done may offer insights on how well an oil filter is doing the job of filtering contaminants, moisture, and metal particles, and whether the filter is permitting 'backflow' of dirty oil. An oil analysis may not provide all the answers as to which oil and/or filter is best, but the test results can be very informative!I used Blackstone Labs for an oil test on my 2003 in August, 2018; the mileage at the time was 109,300 (currently 117,500). I have always used a Motorcraft oil filter and Motorcraft Syn-blend 5W-20 oil, per the manual; oil and filter are changed every 3000 miles. (Yes, old school! The report showed much lower levels of 'elements' than expected for an engine of that age and mileage and a level of 'insolubles' (marker of efficiency of oil filtration) at a very low 0.2%. The oil analysis is not expensive; all the details of cost and how-to are on Blackstone's website:https://www.blackstone-labs.com/This link is to a description of how the Blackstone oil analysis is done:Used Oil Analysis - Bob is the Oil GuyThere are other oil testing labs; a search will bring up options if one chooses not to use Blackstone. YMMV, as always. 2 Likes
Re: Oil Filter Recommendation Reply #6 – February 17, 2020, 01:34:03 pm Oil geeks really get into the details, but a lot of what you read is shade-tree logic and not always technically informed. My strategy is to avoid the noise and pick something on the higher end of whatever brand I'm considering. For example, lots of people like to slam Fram filters, but I have a hard time believing the Ultra Synthetic 20K mile Fram filters are going to fall apart while I'm cruising down the highway.I tend to pick the premium version of whatever brand is on sale.Rich'03 MB in NC 1 Likes
Re: Oil Filter Recommendation Reply #7 – February 18, 2020, 10:02:52 am I'm under the opinion that Ford knows best what is good for their products. I'm thinking they have spent a few more dollars on research and can be sued then any you tuber .....Just SayingGlen
Re: Oil Filter Recommendation Reply #8 – February 18, 2020, 10:45:47 am "Walmart usually has the best prices on oil..."---Walmart does have the best prices, and is the only place around here that stocks on Motorcraft 5W-20 and the Motorcraft FL820S oil filter. The Ford garage charges about $100 and I have to drive across town and then sit and wait for a few hours; Walmart is under $40 for the whole lot. The last time I went in to pick up oil, a young fellow with a startling collection of tatoos insisted on carrying the 5-quart jug (I managed the 1-quart and the filter ) to the checkout for me because he 'always carries things for his grandma'. 3 Likes
Re: Oil Filter Recommendation Reply #9 – February 18, 2020, 11:02:44 am Another question ease. Stick with conventional or go to synthetic oil? On the filter I am going with the Mobil 1
Re: Oil Filter Recommendation Reply #10 – February 18, 2020, 01:00:46 pm Depends on who you ask. Ford likes it's own Motorcraft blended so you should stay with at least a blend. Super Tech synthetic (Walmart) is competitive in price with Motocraft and has a high rating according to my internet research. A factor is the mileage you will run up between changes along with the time interval. Some don't mind paying the price for oils like Mobile 1 for the piece of mind. I go with Motorcraft oil and filter since my changes are twice a year with low mileage. I'll add that changing it yourself is a big plus for the cost savings and knowing for sure what oil is going in. Frank 1 Likes

On the filter I am going with the Mobil 1The semi-synthetic Motorcraft 5W-20 is perfectly fine, you can see from Joan's oil analysis that it does a excellent job of protecting the engine, along with the Motorcraft filter. Ford evidently has a handle on the, oil and filter situation, it is their engine. Joan is religious about 3000 mile oil and filter changes intervals. I know of no one else who takes better care of their LD.I mostly run longer oil changes, around 5000 miles, especially on long trips where finding someone to change it can be a hassle as well as not knowing how good a job they do. I would rather do it myself at home and use Mobil 1, the same oil I have run in all my vehicles for over 25 years and have never had an oil related breakdown with Mobil. The engines I have disassembled, after long-tern use of Mobil 1, were spotless with little bearing or cylinder wear.In the fleet testing I was involve in, Mobil 1, and other synthetics, were still in excellent shape at 7000 miles and could be run to 10,000 miles without problems. We settled for a 7000 mile/ 1 year change interval for the fleet at LAX just because we wanted to fully inspect the vehicles at least annually.Synthetic oil may be overkill, today's conventional oils are superior to those of even a decade ago, modern engines have precise lubrication needs that older oils can't satisfy, The OEMs and SAE (Society of Automotive Engineers) keep upping the motor oil's specifications, with 19 revisions since 1975.J300: Engine Oil Viscosity Classification - SAE InternationalMany cars today are now require by the Owner's Manuals to use synthetic oil only, including our Subaru, due to synthetic's ability to run at much higher temps and with tight clearances. Vehicles with turbochargers need synthetics, they are hell on oil, with the turbos running at extreme temperatures. Synthetics are the only oil that can handle the temperatures, it was originally created for the early jet turbine engines.Today's oils are engineering marvels.Larry
Re: Oil Filter Recommendation Reply #12 – February 18, 2020, 04:45:47 pm Mindispower (I wish we had a proper name to use to address you),This topic seems to have evolved into a well meaning conventional oil vs. synthetic blend vs full synthetic oil. But most folks seem to be missing the point that your rig is either a Chevy or GMC and NOT a Ford. Even you can't seem tell what engine is in your rig; in your initial post in this thread you state is is a 7.5L and in your signature line you indicate a 5.7L engine.Back in 1989/1990, I think GM called for either a 5w30 or 10w30 oil. It may be on the dipstick. I would go with whatever GM recommends. As for an oil filter, there should be a reference to an AC Delco filter in your owner's manual. If buying Fram, I would use one of their "Tough Guard" or "Extra Guard" filters. Steve K 1 Likes
