Can DexVI be used in a 1998 Aisen-Warner AW30-40 (Volvo) automatic transmission originally spec'd for DEXIII? Are there any issues with seal compatibility? Thanks, DEWFPO

There are pros and cons to changing your oil when it Hot, or when it's Cold or somewhere in between. Is the any data to show more contaminants are removed from the engine when the oil change is performed when the oil is Hot? or Cold? or Warm? Sometimes my only real option is to change it when...

Crawled under the Silverado HD today to scope out the impending oil/filter change and cursed the GM engineers entire time I was under there. Anyone installed a remote oil filter on their 8.1L? If so, what brand did you use, are your happy with it?, where'd you move the filter to? Thanks, DEWFPO

I just ordered this truck, I am hoping it will be here by the end of the year. I will be changing to synthetic oil and have 3 questions for this board. Note : I will not be putting fast, high mileage on this rig and it will only be driven about 2-4 times a month but when it is driven it will be...

Does anyone have any experience with DEI's Radiator Relief? Good or Bad? Thanks, DEWFPO

A freind of mine had a Chevy Astro van he bought used. He says his cyl. #6 has low output at idle and above idle it seems fine. He said it has 90 lbs. compression in #6 but didn't check the others to compare. No unusal sounds coming from the engine. He says there's a known problem with these...

I'm in the market for a new truck to replace my 20 year old Ford 'old faithful'. I've read quite a bit about piston slapping in newer GM vortec engines on this site. I am seriously considering buying a new Chevy truck and am wondering if anyone knows if GM has solved the piston slapping issues...

I have a vehicle that has a startup tapping issue(characteristic of this model), but I would like to install a bypass filter as well. The only place I can install a bypass filter is about6 ft. of hose away and about 12 inches higher than the stock filter. I am considering putting in a very...

Which style is better? Why? It looks like tube and fin should have less resistance to flow but many stacked plate manufactureres are calling their designs LPD (low pressure drop). Which are the best stacked fin atf coolers out there? Someone once mentioned a particular brand that compensates...

I know what Port Fuel Injection is, I know what Central Fuel Injection is, but what the heck is Sequential Fuel Injection? Thanks, DEWFPO

1986 Honda TRX200SX. 4 stroke, 5 spd, auto clutch. Factory manual says use Honda 10W40 dino oil which I do. I have always been told that I cannot use synthetic oil in this engine/trans. because of the wet clutch. Lately I have been seing syn. oils like M1 motorcycle oil that says it is o.k...

I was in the AutoZOne in Grand Junction, CO on Wednesday. They had Castrol Syntec 0W30 with both a RED label and a YELLOW label. Neither said "MADE IN GERMANY", in fact they both said something about being made or blended in the US and it is not to be sold outside of North America. Neither was...

Scenario : Long uphill grade of several miles. Transmission is in 3rd gear with no lockup, engine rpm 2,800. Obviously this is going to build up heat in the trans because of the slippage (w/o lockup). Two questions about the above scenario : 1.) Is less heat built up in the trans with HIGHER...

I'm confused. Neutra or Auto-Rx, What are the Pro's / Con's of each. I see them sometimes mentioned interchangeably on this forum and am not sure which one I should use to clean up an engine with over 100k miles on it run on dino oil changed every 5k miles. The car was not driven hard and is a...

I'm replacing the 16.5 hp Tecumseh engine in a friends lawn tractor with a new engine. He blew the original 17 hp Tecumseh when the govenor failed and over-reved till it threw a rod. It didn't occur to him to turn the key off while the engine was over-reving........ I have no manual for this...

Can anyone tell me exactly what the difference is between the M1 SS vs. TS? I have about 6-7 gallons of M1 TS that I'm slowly using up but it may take me a couple of years. I was just wondering if the SS is that much better?
