Oil Filter

[Guest]

Today I changed the oil filter in my Landrover Series 2a 2.3 petrol engine and couldn't help but notice the size of the oil filter compared to that of the 3 litre Stag engine. It is at least twice the size. Even the 1.8 MGB engine has a larger filter. Does the small Stag filter contribute to the very high engine oil frequency - every 3000 miles? Would a remote and larger oil filter lead to a higher mileage between oil changes?

Hello hamstag
I don't know what effect fitting a larger filter might have but you might like to note the Lubrication schedule Triumph published in the Triumph Stag Handbook.
Weekly or before a long journey.Check Engine oil level
3000 mile service. Check/top up Engine oil.......(or after three months)
6000 mile service. Renew engine oil filter. Renew engine oil.

But elsewhere : Owners are strongly recommended to change the engine oil every 3000 miles or three months if the car is frequently driven for long periods at high speeds approaching the operating maximum.

However engine damage in a Stag is a costly thing so changes at 3000 miles with a good oil are good practice.

I've had my stag for almost 6 months now - changed the oil when I got the car and then changed it 3 months later, having hardly done 500 miles! I'm quite willing to change the oil and filter as per schedule, however the smallish oil filter certainly looks like another case of under engineering.

I've heard many criticisms aimed at at the TV8, some justified, many not but never heard that one before.

John, you have only got to look back at the documented failures because of this issue

HNY to you, and everyone else

HNY---huh. I'm now paranoid about my small bowl. Someone should have developed a bigger one.

The biggest advantage I can see to a larger filter is better filtration.

I have read that the bypass valve in the filter opens at a relatively low rpm as the small filter cannot pass all the oil flow at high rpm or when the oil is cold. This must increase the chance of unfiltered oil passing through the engine.

The more mileage the engine covers between filter changes the more chance of the filters flow capacity being reduced.

I'm now using this filter after Graham did an autopsy on different filters. http://www.ebay.com/itm/301331544124...%3AMEBIDX%3AIT

My oil pressure increased considerably after fitting it. It's about 50% longer than the other canister I was using not that I was worried about the other one or my previous oil pressure.

Same here I have been using th HP-2009 for the last coule of oil and filter changes no complaints so far.

Koy. A spin on adapter is the simplest way to be able to fit a larger filter, and make the job of changing it so much easier as well. I fitted one about 15 years ago and have always used the filter that was common to most Volkswagens at the time, which is almost twice as large as the original. The larger filtration area must reduce the risk of the (built-in) pressure relief valve operating when the oil is cold, but I would still recommend that you change the oil at least every 5000 miles, or once a year. If you take it off the road for the winter, that is the best time to do it.

Another HP-2009 convert here. Fitted one a few weeks ago at the last annual oil change. Seems OK so far. Listed for many 3-litre engines.

Mike, I use a spin on as well, but have always used the standard filter. Which one would you recommend please?

Thanks, Rob

Dave,

Could be a mistake but the vehicle compatibility does not fit a Stag.

I though I would butt in, Happy new year. Its the way the filter is constructed is important. Most filters have the bypass valve fitted at the bottom of the element so when the engine is cold and the oil is thicker or if the filter becomes partially blocked the bypass valve opens and the oil then passes around the outside of the element ( washing it)back into the engine thus taking any collected debris with it. Two makes of filters that have the bypass valve at the top of the filter are K&N ( my choice) or WIX the bypass valve works the same way but when the valve is at the top the oil passes straight back into the engine and does not flow over the outside of the filter element. While the valve is open the oil does not get filtered but by the same token it does not carry debris back into the engine either. I hope this helps to explain.

It wont list a Stag as it was not fitted with a spin off filter as OE. Happy New Year Jeff.
