NEW YORK (

TheStreet

) -- "Oil just refuses to go lower," Jim Cramer told the viewers of his

"Mad Money"

TV show Tuesday. He concluded that if you can't beat them, join them, which is why he recommended that every portfolio include at least one oil stock.

For the conservative investor, Cramer once again recommended oil and gas pipeline master limited partnerships like

Kinder Morgan Energy Partners

(KMP)

. He said that pipeline MLPs act like a toll road, charging for the quantity of oil and gas they transport regardless of the price of the underlying commodity.

For more average investors, Cramer said to consider oil drillers like

EOG Resources

(EOG) - Get Report

,

Range Resources

(RRC) - Get Report

or

Cabot Oil & Gas

(COG) - Get Report

, three stocks that he's recommended many times on past shows. All of these names, he said, have be rallying as the price of oil has continued its rise.

Cramer also recommended oil service plays like

Schlumberger

(SLB) - Get Report

and

Ensco

(ESV)

, two stocks which he owns for his charitable trust,

Action Alerts PLUS. Also making the list,

National Oilwell Varco

(NOV) - Get Report

, a stock Cramer said should be bought in stages as it trades wildly.

For the risk-takers, Cramer was bullish on names like

ConocoPhillips

(COP) - Get Report

,

Chevron

(CVX) - Get Report

and even

Occidental Petroleum

(OXY) - Get Report

as well as companies like

CoreLabs

(CLB) - Get Report

,

Halliburton

(HAL) - Get Report

and

Baker Hughes

(BHI)

.

Cramer said he's still not a fan of

Transocean

(RIG) - Get Report

, as the company issued stock today below the prices it's been buying back shares and will likely see its dividend at risk soon.

"Give your portfolio a boost," Cramer concluded, you have to own an oil stock.

Sick Euro

In the Off the Charts segment, Cramer went head to head with colleague Tim Collins over the chart of

CurrencyShares Euro Trust

(FXE) - Get Report

, the ETF that tracks the strength of the euro vs. the dollar.

Collins' first chart was of the correlation between the

S&P 500

and the euro. He noted that since October our markets have been trading in lock-step over 50% of the time, and more recently 84% of the time. The euro is clearly in the drivers' seat, said Cramer.

Turning to a daily chart of the Euro Trust, Collins saw a wedge pattern, a bearish signal, with the added bad news that the floor might not hold, thanks to light volume at that level. Collins also noted an ultra-bearish arch pattern between October and November, one that could turn into a "cup-and-saucer" pattern, also bearish.

The weekly chart was just as bearish, showing the euro trading in a channel, one that has recently broken down with the relative strength indicator pointing to continued weakness. The monthly chart, also bearish, with stochastics signaling that the currency has a long way to fall before becoming oversold.

Cramer said with all of these signals pointing downward, the euro remains untouchable at this point. He continued to urge investors to stay cautious and migrate into more conservative stocks.

Farming Sweet Spot

Continuing with his "Stocking Stuffers" series of stocks that work even if Europe doesn't, Cramer recommended

Tractor Supply

(TSCO) - Get Report

, a rural purveyor of farm, ranch and home goods for smaller, hobbyist farmers.

Cramer explained that Tractor Supply is in a sweet spot with its 1,054 locations across the U.S. He said the company doesn't suffer much from online or big-box competition given its rural and outer suburb locations. Plus, the company's core demographic is faring better than the U.S. population overall, with average household incomes rising 2.3% vs. a decline overall.

Tractor Supply is growing its store count by 8% to 9% a year and is also testing a smaller store format that, if successful, could raise the company's growth potential even more. When it last reported, Tractor Supply posted a six-cent-a-share earnings beat on a 17% pop in revenues. The company posted same-store sales growth of 11.5% and it was able to raise guidance to boot.

Trading at just 20 times earnings with a 17% growth rate, Cramer said Tractor Supply is inexpensive, but he would still buy it in scales as the markets trade in lock-step with Europe.

Intriguing Speculative Energy Play

In the "Executive Decision" segment, Cramer sat down with Charif Souki, chairman, president and CEO of

Cheniere Energy

(LNG) - Get Report

, a speculative company that's working to build the country's first natural gas export facility due to be completed in 2015.

Souki explained that the U.S. is now exporting a lot of commodities that it used to import just a few years ago. He said things like coal, propane, butane and soon natural gas are all being exported from the U.S. Souki noted that two recently completed terminals to export propane and butane are already running at full capacity.

Why the sudden change? Souki said that five years ago, after Hurricane Katrina when prices for oil products shot up, everyone started drilling. "Price motivates technology," he said, which is exactly what the natural gas market has seen with hydraulic fracturing. The U.S. has also made other changes, noted Souki, and our country is already importing 700,000 fewer barrels a day of oil than it used to.

When asked about his company's needs for additional financing, Souki explained that his company operated under a master limited partnership model and much of the fundraising will be done at that level.

He said Cheniere needs $5 billion in additional funding and will get $3 billion from the capital markets and the other $2 billion through equity offerings. Souki noted that Cheniere is set to receive $865 million a year from its contracts and could generate an additional $700 million annually by selling excess natural gas that it will have access to.

Cramer called Cheniere a speculative company, but an intriguing one.

Stay Away From Airline Stocks

In his "No Huddle Offense" segment, Cramer warned investors not to be tempted to buy airline stocks.

Cramer said that he's been on six flights recently and despite paying through the nose, sitting on packed planes and getting absolutely nothing for free, there's still no reason to buy an airline stock.

"The airline business is a nightmare," he explained. Packed planes are not a sign of prosperity, he said, adding the industry is driven by rising labor and fuel costs and has no margin for error. The industry also struggles with constant fleet upgrades to meet rising safety and fuel efficiency standards.

"Don not be tempted," he concluded on the eve of the

AMR Corp

(AMR)

, parent of American Airlines, bankruptcy filing. You simply cannot own an airline stock.
