The lack of phosphorus and zinc in current oil blends is catastrophic to engine longevity. Now my problem is :when it's down;how much is it down. If you know you have a 5 quart pan, any aftermarket dipstick dhould work. Zinc is needed for proper valvetrain lubrication in older engines there is no zinc in delo or rotella anymore hate to tell ya, if you don't believe me check From my research on oils,I can find nowhere that zinc has been banned. If you don't like what you see switch to the next higher grade. Carmakers pretty much unanimously agree that 5w-30 and 10w-30 are the best.
Has to be changed for cold and hot weather temps to a different weight. They still have plenty of zinc for the older engines. The higher viscosity helped maintain better oil pressure. Just needed opinions on this vehicle Posted via Mobile Device from crower site: Use of Synthetic Oils Crower does not recommend the use of synthetic motor oil in any application, particularly in hydraulic and flat tappet camshafts. I have seen the cam manufacturers all seem to require the use of an antiwaer additive I'm assuming a lead for cam break-in. I didn't feel any performance differences. For additional information on oil, click here! The thinner oil also helps manufacturers meet the demands of minimum mileage set upon them by the government.
I had a junkyard dipstick from a 305 in my 350 and whenever it read a quart low the pump would cavitate. The Ford I mentioned takes 6 quarts also. The switch ha a plug connection ,it's secured by 2 hair-pin like snaps. On the other hand, if you're dealing with a new crate engine or a total rebuild, then it might be something to consider. I'm sold on synthetic, and have for years.
By that I mean a truck only site. Viscosity extenders replace the oil, so that means less real lubrication per quart with the extenders. This was in the 70's and the test was scheduled to run for several years. This guy has vast amounts of knowledge and certified in every aspect of the automotive field. Anything with larger numbers than that get the larger numbers by adding viscosity extenders to the oil. My rule of thumb for the oils is, I stay with one brand.
While holding the chrome casting on the front of the dash unscrew the sw. Thanks for the replies everybody! Synthetics are also chemically made and have no minerals. Another thing he mentioned was there is no harm in switching back and forth between the two, it's just when you have to change the oil that makes the difference. The dipstick never seemed right. The minimum gains in horsepower are offset by the excessive wear to cam and lifter surfaces.
My thought process was flawed again! Conventional oil is made from minerals and has a running life span of about 6000 miles the myth of changing oils every 3k was brought around by the companies producing the oils. Two of the V-8s were diesel fueled one produced 148-horsepower and the other produced 135-horsepower , with a displacement of 379-cubic inches. The remaining three, eight-cylinder engine types were a 170-horsepower engine with 305-cubic inches of displacement, a 210-horsepower engine with 350-cubic inches of displacement and a 230-horsepower engine with 454-cubic inches of displacement. It seems that in all I have read that some zinc is still included in most oils and that other anti-wear additives have been included in at least some. Five, eight-cylinder engines, as well as one six-cylinder type were available for 1987 Chevy pickups. These features included chrome bumpers and hubcaps, a silver-colored plastic insert for the grill, and silver-colored door handles and side-view mirrors.
Also, what say you about synthetic? About the time the synthetics started hitting the market,I took several industrial lube classes and never was taught that there was any difference in lubricity. Read the owners manual of your new fuel injected 4 and 6 bangers. ??? I had to make my own marks. I have no problem running conventional, blended, or fully synthetic. Like many answers, that depends. Carlisle is near here, and several times per year thay have large car shows that draw nationaly.
I don't switch brands off oil. He made sure he brought up the fact he was around when synthetic oil was first introduced in the 70's. I have 2 questions: 1. I have a 6 quart Corvette pan on my 32 and I shortened the oil tube stick. That would be for aircraft usage.
