Not at all. The PTFE particles in Tufoil so small, they pass through the filter as if it wasn't even there! Bulk filters that use the big wads of cellulose or edge on toilet paper rolls, filter fine. Yes. However, If you have an old classic that ran on oils before 1950, we recommend taking the engine apart and physically cleaning the sludge out of the crankcase and out of the valve covers before using Tufoil. A high detergent oil can stir that material up and cause problems.

Many old engines show signs of oil burning. Tufoil can help in some cases by freeing up partially sticking piston rings. There have been some dramatic improvements reported from the field where Tufoil freed up the rings and they started working properly again. However If the rings are cemented solid in their grooves or the cylinder is scored, no lubricant can eliminate the smoking.

The best way to ensure proper oiling is to use our squeeze bottle recharger kit (Part No. 99-5050). With a squeeze bottle, you simply run a bead along the top of each pleat on both sides of the filter. If using an aerosol recharger kit (Part No. 99-5000), make one light pass over the entire filter area front and back. The oil will then be evenly absorbed throughout the rest of the cotton medium over the next several minutes.

come onto the market recently; they are different from the moly-based additives that have been around since the early 50's. PTFE is the chemical name for Teflon(TM), a trademark owned by DuPont. In general, auto manufacturers do not recommend use of these products. Most USENET responses to questions on these additives are favorable (slight increase of MPG after application, smoother revving) but long term results (whether PTFE additives are effective after 5K miles) are debatable.

We recommend 8 ounces of Tufoil as an initial treatment when you change your oil. (This would be for the standard 4-5 quart crankcase...less for smaller engines.) After this initial treatment, just 4-ounces of Tufoil added to the crankcase at each oil change is sufficient. The basic guideline would be 2 ounces for each quart as an initial treatment and 1 ounce per quart at each oil change after that.

I've just bought an alternative oil filter element for the Daytona for about a third of the original Triumph price. It's from Meiwa, designed for all Honda 4 in line engines and Kawasaki K400/440/550/650/750, ZX550/600/750/900/1100 - cost about $6. The included rubber O-ring seals don't fit, so you have to get the original Triumph parts: #3600025 (large) and #3600003 (small), about $1 each.

We recommend customers who drive in a city environment where there's lots of stop and go driving to change the oil and filter every 3,000 miles. The main reason we recommend 3,000 mile intervals is that driving in stop and go conditions causes excessive unburned fuel and carbon build up causing your engine oil to become contaminated. Oil is the life blood of your engine and changing it frequently will increase the longevity of your engine and reduce the potential for major mechanical failures.

When you first convert from the use of petroleum motor oil to the permanent SynLube™ Lube-4-Life? lubricant it is important that you also change the oil filter. Only SynLube™ Lube-4-Life? MicroGlass or other premium quality Original Equipment Oil Filters should be used whenever possible. MicroGlass or Synthetic Media are also available in various quality levels from AC/DELCO, Fleetguard and Hard-Driver. The popular FRAM filters are not very good.

Micro-abrasive blasting requires clean dry air to work effectively. Oil contamination will cause irregularities in the abrasive flow by forming clumps above the orifice or in the nozzle. Proper protection from oil is especially critical for MicroBlasters that are connected to a shop’s compressed air line. Often oil is added to air line for pneumatic instrument lubrication. Older piston compressors tend to have leaky O-rings, putting oil into the air stream.

The Airbox and airfilter are important parts of your bike. Clean air improves the combustion process, and the airbox helps reduce the noise from the engine. Keeping your filter in good condition helps with the combustion process, and checking the airbox can help identify problems with the bike (such as too much oil). The other thing to keep in mind with the airbox, is this provides the air intake into engine. This is important when going through water.

The very late T's may have had an oil filter. Look under the oil pan. If there are 4 bolts in the middle of the pan then it has an oil filter. If there are only bolts around the perimeter of the pan then it does not.

The vast majority of oil filters used in automobiles today are full flow filters. With this type of system, all of the oil is filtered before it passes into the engine. Full flow filters must provide low restriction to oil flow while having a high degree of single pass efficiency. This means that a filter must remove as much engine-damaging dirt and grit as possible from the oil on the first time around. Pleated Media.

Oil Pressure Regulating Valve. The oil pump pressure regulating valve, usually built into the oil pump, helps control the operating pressure of the lubrication system. The regulating valve is set by the manufacturer to maintain the correct pressure. The valve utilizes a ball (or plunger) and spring mechanism. When the operating pressure is below the preset PSI level, the spring holds the ball in the closed position so that oil flows to the bearings under pressure.

Be sure to properly containerize the oil and oil filter. There are numerous convenient locations in Western Placer County were you may properly dispose of your used oil and used oil filters. Click on Used Oil to find the location nearest you.

Tufoil is too slippery to use in automatic transmissions. The oils in them need to be a bit grabby or the clutches won't work properly. In manual transmissions, about one part Tufoil in ten parts high-grade transmission oil will make them run cooler and shift smoother.
